I came back to apologize for telling you to "shut up." I don't think it was worded too too rudely and necessarily requires an apology, but that's not my style, either. I just lost a ton of karma on this (not that that matters, but it stings a bit!) and felt like a lot of people were attacking me on disingenuous grounds. Anyway, I do appreciate the apology, so thank you!
Your point about depression is actually quite interesting. My personal belief is that your emotions reflect the mental content of your mind. So if something is making you depressed, you need to think about what's wrong with the ideas you hold that's causing you to be depressed, and change your ideas. It seems to me that if you just treat it with medicine, the underlying wrong ideas will potentially linger. (OTOH, I've heard it said that taking the medicine gives you strength to confront the things that are bothering you when you lack it.)
FWIW, I haven't been able to confirm or deny my belief, but I suspect it's basically correct, but that not all people can address the intellectual disconnects they have in all situations without some form of outside help.
