What the hell

If this is clinical depression, it must last for six months (DYSM IV) , so I can be sad or even depressed for some time before it is defined as a mental disorder.

Remember, you don't have to wait for an official diagnosis to know you're feeling bad, and start trying to do something about it.

"Stream on conciseness", or stream of consciousness?
Either way, it sounds like you've got a handle on it, and finding a way to cope. Good for you. Keep on fighting, you're worth it.
