Sportsdude.....if NOTHING else, I'd SO want you to get over feeling ashamed. There IS no shame in something that could be as simple (?) as a chemical imbalance that you have no control over.
primefactor, I didn't get from your comments that you were in any way suggesting it was as simple as 'shaking it off'. It's pretty clear you're much more intelligent than that. Your belief that one must do SOMETHING to act, is bang on. But I believe you need to at least establish if it's psychological or chemical, because that is the deciding factor that would allow one to take those healing steps.
