Hang in there tight girl. There is more to life than getting depressed at how people don't seem to like you.

If you think you are a bit on the chubby side, I would strongly recommend to start some kind of exercises like sports or hitting the gym. It will make you feel happier and better (at least while you are exercising). I was in your status once, I felt worthless, needy, etc. Then I have started working out at a gym few months ago and I found that I started to feel more attractive and confident. And now I feel that life is wonderful again.
