I think you could move to America. It's practically right there, and people are generally pretty nice and accept you for what you are. (usually)
Just don't move to a big city...
The only reason why I ruled out America is Trump. Rent isn't an issue as long as I can live with another community member until I am allowed to work and split the costs. But again, it depends since there are chances that I am gonna be permanently disabled or partially. Healthcare insurance costs would also be a serious problem.
As for Europe it would have to be a country with free healthcare and with proper support for autistic people.
