I'm So Stressed

Time to study? No, time to write.

I don't even know what to say. I'm just counting on writing to make me feel better.
I definitely need some self-confidence right now. I don't know if I lack it because I'm just stressed or what. Work has slowly degraded any positive self-image. Then there's finals. The probability that I will fail statistics. And that I've trained myself to have no outward signs of stress. I don't really act stressed, I just stop thinking. and sleeping. and eat twice as much. It really sucks. and I want out.
And it bothers me that my closest friends are all far away.
And suddenly I don't know what I'll be doing this summer, or where I'll be.
I sometimes think I was better off years ago, being purely myself, with friends who thought and believed the same as I did, doing anything that I wanted to because I wasn't scared in the slightest. I was probably cocky at times, and maybe inconsiderate, and far more stubborn. But the confidence was there. I would rather be overconfident and plunge head-on into something I don't know enough about and have to figure things out the hard way than be too timid to get in deep at all.

I've lost my muchness.

:(
How terrible. How does one go about regaining one's muchness?
I suppose sleep would help. I can't hardly concentrate on what people are saying anyway. or what I should be doing.
Also, I need to get out and do something physical. Seriously.
I don't know what else to do, so I'll start there.
