Yea go get some sleep man. And when you wake up later today eat something healthy, then go find something to do. Don't just surf the web, it's bad for you!

Find something that makes you feel important. Try the animal shelter again. If they aren't looking for volunteers see if you can find a local horse farm, they always need help.

...... See I can be nice to you bro!!

I've been there man..... occupy your mind, it will help.
