impostor syndrome, but it's my autism diagnosis :( help?

I recently got my autism diagnosis in january, but I'm having a really, really, really hard time accepting it. not because I think it's a bad thing or anything like that, but because I've been misdiagnosed soooo much all my life that I'm now struggling to accept this one.

I've been misdiagnosed with BPD, psychosis, schizotypal, ocd, and a lot more (which I am aware overlap with autism) but it's just so hard.

I don't feel like I'm "autistic enough" (I'm also aware it's a bs statement but I can't help feeling this way) and I'm afraid I'm being misdiagnosed again and being an impostor in the community???

I've been spending hours researching and reading and doing quizzes to make sure I actually am autistic, but no matter how high the score is or how much I relate, or how much people who know me say that yes, I am autistic, I feel like. an impostor.

i could rant about my traits and symptoms but I feel like I'm already going on for too long. idk what to do (':
