In the diagnostic process and terrified that I don't have autism after all

Don't get me wrong, of course autism is a big deal and it's not easy. I don't wish to be autistic but it's just such a relief to have someone that might explain why I am like I am. I can breathe a little easier and I am kinder to myself. For some reason it's easier to say I need a bit of accommodation because I am autistic instead of saying I need it because I have "regular anxiety". I am so scared the professionals will say I am not autistic because I can just identify with it so much.
