There's plenty of positive advice here, so I'll write some negative things. If you feel like the therapy is not working for you, as people have pointed out, change therapists. Go through multiple ones, don't give up!
The reality still is though, that therapy isn't a magical cure that fixes everything. Depending of your problems, it might not work no matter how many therapists you go through, no matter how many years of therapy you do. This doesn't mean you shouldn't try, no - absolutely do try. It also doesn't mean the problem is you, sometimes things just don't go how people say they should.
Therapy has not worked for me; it can't fix my shitty physical health, and it can't fix how unfit to society I am because of my autism. My friend did ten years of therapy, but still killed themselves. There's no cure for everything, not everyone gets a happy ending. But maybe you do; you never know unless you try! That trying is a huge step you can be proud of taking, no matter what.
Autism still isn't a disease though, you can't "cure" it, it's something we are. Even with the most disabled we should start with accepting them and offering the help they need, not just immediately label them as defected and try to erase who they are.
