Have any of you recovered? And if so how?

I thought I had recovered. I moved across the world to a different country where no one knew me. Did volunteer work. Discovered a job I was passionate about. Met a woman I loved. It seemed like everything was looking up, but then as time went on I slowly sank back into old habits. I am beginning to feel as though it is incurable. That some people will just never find true happiness, and that it is okay not to. Has anyone fully recovered? I am talking a year+ with normal range of emotions.
