I'll keep this brief, since this is not the place to debate 'psychological vs. genetic' factors, with regards to mental illness, but suffice it to say that I have first-hand experience with friends who are diagnosed with the condition, clinically, but have (more or less) opted to "own" it, and work through the condition with thearapy, rather than resort to an expensive pharmaceutical treatment, because they firmly believe they are not "genetically hard-wired" that way. They wanted to take responsibility and accountability for their conditon, because they believe it was brought on by social and envieronmental effects on their persoanlity, that they can "unlearn".
As somebody with no experience in professional psychology, I can't assess how well they're recovering.
As a friend and loved one, I'd say they're dealing with it fairly well.
