I think I may be autistic

So I think I may be autistic but can’t afford to seek a diagnosis because it cost anywhere from 1-5k.

I’ve listened to audiobooks on it and taken diagnostic tests on embrace-autism.com. Which I always score high on. I almost cried listening to the book Unmasking Autism because I’d never felt so heard or understood in my life. And now all my anxiety, feeling overwhelmed, confused and lack of social understanding all make sense. But my problem is how do I get people to understand?

I recently made a social mistake. Usually I put so much effort in not doing that but the day before was extremely stressful and I was so overwhelmed/ filled with panic all day- well my bfs dad sent him a long paragraph about how rude I was and then talked to him at work about it the next day. My bf did try defending me but his dad said anxiety/ burn out/ mental health is all just an excuse.
