Has anybody ever been 'healed' from severe anxiety disorder?

I've always had severe anxiety. I had a very abusive childhood, and I was never able to overcome my severe anxiety disorder. I'm 30 years old. The only time I don't feel the severe anxiety is when I'm drunk.

Do you know anybody who was able to recover from severe anxiety? What did they do?

I'm thinking of cutting off my internet addiction and seeing what that does for me. idk.
