I don't know what to do

I (20 ftm) suspect I'm autistic, but I don't want to risk getting tested and being diagnosed because I don't want to lose any of my rights, which apparently can happen when you're diagnosed with autism which I think is fucking ridiculous (pardon my language).

The reason I'm making this post, is because after having a lot of trauma therapy, I've been able to remember more of my childhood. I remember spinning in circles for a good 30 minutes straight in my room, I still spin in circles to this day. Whenever I would spend the night at my childhood friends house, I would ask if we could play pretend in the exact same scenario, in the exact same dress up costumes, and the exact same words. I had several movie scripts memorized including James and the Giant Peach, Ferngully, Corpse Bride, and The Last Unicorn, which are the movies I would watch over and over day in and day out. Now, I watch WentWorth, Wife Swap, and Ghost Adventures day in and day out. I have always hated certain colors like any shade of Yellow, bright oranges, and bright pinks because they hurt my eyes and make me incredibly overstimulated. They still do. I can handle certain loud noises like music, I can listen to loud music until my eardrums bust, but God forbid there are overlapping voices.

These are just a few of the reason I suspect I have autism. Not even mentioning my special interests, problem with oversharing, and more. I didn't think I was autistic for awhile specifically because I dont have problems with eye contact, I said my first word at around 3-4 months old, and I don't have a monotone voice. I don't want to self diagnose, because I feel that is unfair to the people who have worked so hard to get diagnosed, but I don't want to lose any of my rights. I'm already on disability, life is hard as it is. I guess I'm just looking for ways to make my life easier. Obviously, it's going to be my own special journey, I just don't know where to start. I don't even know if I should be on this subreddit.

Anyways, sorry for my word vomit. I hope somebody can at least relate to this.
