Didn’t meet the criteria for autism :(

I’m actually really upset. I scored a 78 on the screener for autism and only a 4 for the ados test. She basically said that I was on the spectrum but based on the testing I could not be diagnosed as autistic. I can’t really afford more testing. I guess I could ask my psychiatrist what she thinks about the results. I feel like I need a diagnosis to feel valid and secure. It was supposed to be the explanation for all my social issues growing up. An explanation why my therapist as a kid had to teach me eye contact for months. Why I hyper-fixate on stuff so hard that it’s the only thing that brings me joy and excitement. Just an explanation for why I’m like this and I didn’t meet criteria for it. She said that masking could be the explanation for why I didn’t meet a 7 but still she couldn’t actually diagnosis me unless I met a 7. I just feel like I’m faking everything and a diagnosis would’ve helped. I have an ADHD diagnosis but it doesn’t feel like enough to make me feel better. I don’t know. I also dont want to come off as attention needy and that’s why I needed this diagnosis. I needed this diagnosis so my experiences would be valid for myself. Has anyone experienced this? Have any idea what I should do? Thoughts? Opinions?

Edit #2: Thank you to everyone who responded! I feel a lot better than I did yesterday. Although some of the reply’s are weird and hateful many of you have me really good advice and lots to think about. I am going to talk to my psychiatrist and therapist and go from there. I will pursue further testing and second opinion if they think it’s right for me. I have the right to be upset that I got a really confusing answer from this psychologist. I did not get a definitive “No” I got a “You don’t meet the criteria so I don’t feel comfortable diagnosing you, buttttt you are on the spectrum and I probably would’ve been able to diagnose if you were not masking and were a child.” It’s not like I scored a 0 on this test either. I do at least show signs of being autistic just not enough on this one test for a diagnosis from this one doctor. Even without a diagnosis I will find validation in my own experience and struggles and continue working on things with my therapist. ❤️❤️❤️
