I know how you feel. I have Seasonal Affective Disorder, and become extremely anxious and depressed around winter time. I can't sleep, and when I do get to sleep, I wake up an hour later and can't fall back asleep. I can't focus and I forget things. I daydream constantly, and I get headaches and other pains on my body. I have panic attacks. Are you taking any medication? Paxil works alright for me.

One thing I find that really works is turning my stereo up full blast and just dancing around like crazy LOL.

Why don't you start a new business? Is there anything you're good at making that you could sell? My friend buys things and resells them, and he makes lots of money. You could try that.
