u/Cautious-Fun-2402

I'm 17 and I've been doing horribly mentally for YEARS and I've been begging for help for years from teachers, parents, and friends and literally everyone has just blown me off. I thought reaching out for help was supposed to work. I just want to feel better. I told my mom I wanted a proper autism diagnosis and she kept telling me "schools almost over, you have good grades (which has never been true) why does it matter?" And I just don't know what to say to her. She's convinced I just don't have these problems that have been present my whole life. I had a breakdown and I started hitting myself and I wasn't able to talk and she called me insane and crazy and just yelled at me for like 30 minutes while I sat there unable to talk. She told me she's trying to get me help at the doctor's but it's been like a year of trying just to get to a primary care doctor with no luck. I feel so helpless I'm about to fail half of my classes my junior year and idk what to do. All I want is support and help so I can do better in school and just in life in general.
