How to get support as an adult autist?

I ask because in the past I've sought support and the professionals always refer me to mental health, which in the beginning yes I wondered if I was mentally unwell but in that time my traits have never changed and they've given me several medications and it never once actually did anything.

So I think I can now safely say all my problems are autism related and as we all know this can't be treated! 

I wish the doctors would take out more time to read up on autism rather than keep trying to dismiss it and treat it. I've been through almost 4 years of them trying to cure my autism and it's caused a great deal of trauma for me along the way.

I feel like I need some support with my autism but I don't know where to go or who to talk to......my doctors keep referring me to mental health and I don't want to go that route again.
