I am formally diagnosed with ADHD but cannot afford an autism assessment. I know I am autistic. Here is why that is enough - and why self-diagnosis has always been valid in our community.
I have a formal ADHD diagnosis. It cost me hundreds of dollars, months of waiting, and a fight with my own imposter syndrome that lasted longer than the assessment itself. And I am one of the lucky ones - I could afford it, I had insurance that partially covered it, and I found a clinician who actually listens to adult women.
But I also know I am autistic. I have known for years. The research I have done, the communities I have found, the lived experience of my entire life - it all points in the same direction. The sensory overwhelm, the social exhaustion, the need for routine, the special interests that consume me, the way I stim without realizing it, the meltdowns that I spent decades calling "panic attacks" because I did not have the language for what was actually happening.
I have not sought a formal autism assessment because I cannot afford it. An adult autism evaluation in my area costs between $2,000 and $5,000. Most insurance plans do not cover it. The waitlists are six to eighteen months long. And even if I got on a list, there is no guarantee the clinician would be trained to recognize autism in someone who has spent thirty-plus years learning to mask so well that even I sometimes forget who I am underneath.
So I sit in this in-between space. Formally diagnosed ADHD, self-diagnosed autistic. And I know I am not alone in this space. So many of us are here. So let me say what I need to hear, and what I suspect you need to hear too: self-diagnosis is valid.
Before we talk about why self-diagnosis is valid, we need to be honest about why formal diagnosis is not accessible to everyone - or even most people.
Cost. Adult neurodivergence assessments are expensive. They require specialized clinicians who are often in short supply. Even with insurance, the out-of-pocket costs can be prohibitive. Without insurance, they are out of reach for the majority of people.
Wait times. In many places, the wait for an adult autism assessment is measured in months or years. During that wait, you are supposed to just... what? Not know yourself? Not accommodate yourself? Not identify with a community that could help you?
Gatekeeping. Many clinicians still operate on outdated, narrow criteria. They look for the "classic" presentation - the young white boy who lines up his toys and does not make eye contact. If you are an adult, if you are female, if you are nonbinary, if you are a person of color, if you have learned to mask - you are significantly less likely to be taken seriously.
Bias and harm. There are clinicians who will tell you that you cannot be autistic because you make eye contact, or because you have a job, or because you are married, or because you "seem fine." Being invalidated by a professional can be more damaging than not seeking the diagnosis at all. It can set your self-understanding back years.
Risk of discrimination. A formal diagnosis on your medical record can be used against you. Some countries use autism diagnoses to restrict immigration, parenting rights, or medical autonomy. Some employers will discriminate. Some insurance companies will deny coverage. For some people, not having a formal diagnosis is actually safer.
When people say "get a formal diagnosis or you cannot claim the label," they are ignoring all of these barriers. They are treating a piece of paper as proof of personhood - and that is not how brains work.
There is a specific experience that many of us share: you get diagnosed with ADHD first (often as an adult, often after years of struggle), and somewhere along the way you start to notice that the ADHD label does not quite cover everything.
The sensory issues are too specific. The social differences are too fundamental. The need for routine conflicts with the ADHD craving for novelty in ways that do not make sense if you only have one or the other. You start reading about AuDHD - the coexistence of autism and ADHD - and something clicks that no single diagnosis ever quite reached.
This is sometimes called the "ADHD-to-autism pipeline," and it is incredibly common. Many of us get the ADHD diagnosis first because ADHD is more recognized in adults, because it is seen as less "severe," because clinicians are more willing to diagnose it. But if you look closely at the statistics, the overlap between ADHD and autism is massive - some studies suggest 50 to 70 percent of autistic people also have ADHD.
If you are diagnosed with ADHD and you suspect you are also autistic, you are not imagining things. The research is on your side. The community is on your side. And your own lived experience - the thing you have been navigating your entire life - is the most important data point of all.
This is a question that self-diagnosis forces us to confront: who gets to decide?
The diagnostic criteria in the DSM-5 were written by neurotypical researchers observing autistic people from the outside. They were shaped by institutional biases, funding priorities, and cultural assumptions about what "normal" looks like. They have changed dramatically over the decades - what was once "childhood schizophrenia" became "infantile autism" became "Asperger's disorder" became "autism spectrum disorder." The criteria will continue to change as our understanding evolves.
If the official definition of autism can change that much in a single generation, then the official definition is not the ultimate authority on who is autistic. It is a tool - an imperfect, evolving tool that reflects the current understanding of a small group of professionals at a particular moment in history.
The real authority on whether you are autistic is you. Because you are the one who lives in your brain. You are the one who experiences the sensory overload, the social confusion, the need for sameness, the overwhelming passions. You are the one who has to navigate a world that was not designed for your neurology. No clinician, no matter how well-trained, can access your internal experience the way you can.
Does this mean that any passing interest or brief identification counts as a diagnosis? No. Responsible self-diagnosis involves research, reflection, community engagement, and honest self-examination. But the key point is that the research and reflection you do on yourself is real. It is not a substitute for a professional assessment. It is a valid source of knowledge in its own right.
Acknowledging yourself as autistic - even without a formal diagnosis - opens doors that were previously closed:
There is a small but loud subset of people - both neurotypical and diagnosed autistic - who insist that self-diagnosis is invalid. They say that "real" autistics are diagnosed. They say that self-diagnosed people are "faking" or "trend-following" or "diluting the community."
This perspective is rooted in ableism, not in science. It assumes that autistic people cannot be trusted to know themselves. It assumes that the medical establishment - the same establishment that pathologized us, institutionalized us, and excluded us from research for decades - is the only legitimate source of knowledge about who we are.
It also ignores the reality that many formally diagnosed autistics were once self-diagnosed. The path to formal diagnosis almost always begins with self-recognition. The idea that there is a strict line between "real" autistics and "self-diagnosed" autistics is a fiction that does not reflect how most of us actually arrived at our identity.
Gatekeeping also disproportionately harms the people who already face the most barriers: low-income people, BIPOC, trans and nonbinary people, people in countries with underdeveloped mental health systems, people who cannot risk a diagnosis on their medical record. When we say self-diagnosis is invalid, we are saying those people do not deserve community, accommodations, or self-understanding. That is not community care. That is exclusion dressed up as rigor.
I have a piece of paper that says I have ADHD. I do not have a piece of paper that says I am autistic. I still know I am both. And I am done apologizing for that knowledge.
If you are self-diagnosed, if you are questioning, if you are somewhere in between - you are allowed to know yourself. You are allowed to use the language that helps you understand your experience. You are allowed to accommodate yourself, to find community, to unmask, to grieve, to heal - all without a formal diagnosis validating your right to exist as you are.
You are not taking anything away from formally diagnosed people by claiming your neurodivergence. You are not diluting anything. You are not faking. You are trying to understand yourself in a world that has given you very few tools to do so. And that is not just valid. That is brave.
The brain you have is real. The struggles you have faced are real. The relief of finally having language for it is real. A piece of paper changes none of that. You knew yourself before the system confirmed it. You would still know yourself if the system refused to confirm it. Trust that knowledge. It has been with you your whole life.
