I'm sorry to hear about that, bigboy. I can empathise with the depressive side of the condition, but imagine the manic side is problematic too. I'm glad you can identify a positive (improved chess awareness) side to it.
Chess players have always been an easy target for psychoanalysts, e.g.:
Chess is "adapted to gratify at the same time both the homosexual and antagonistic aspects of the father-son contest." Ernest Jones, "The problem of Paul Morphy" 1930
Whilst I don't entirely agree with this particular analysis of chess players, I do think many top players have "eccentric" characters, to say the least. Morphy and Bobby Fischer are both good examples.
To be honest, (and I'm only talking about myself now,) to willingly spend a life studying a game that one has no chance of entirely mastering is not exactly sane, is it?
Life is sometimes hard on us. Just imagine discovering you have a mental illness, called Bipolar (Manic Depression) and Hear Voices that is around me that no one else can hear.
It can be Hard trying to play chess when you are manic for some people. But I honestly play better chess and have a better understanding off logical chess and stategy.
