Re: sigh, I don't know how much more I can handle...
It could be depression, but it sounds like there's something causing the fatigue - and the fatigue and lack of energy is causing the depression symptoms, kwim?
I wouldn't jump to trying anti depressants right away. I'd request a full blood panel done, to check for platelet levels, thyroid hormone levels, and iron levels. See if anything pops up there that should be supplemented for.
If that doesn't help, then try anti depressants. It just really sounds like there's something else going on causing it all.
