I feel ugly and awkaward and depressed and I can't get a guy to notice me help!!!?

How old are you? Relax.....I'm sure you're beautiful. If you aren't happy with your appearence, change it. Try to work out. If you want to put on weight, eat higher calorie foods that are healthy for you, and more frequently. You can also try to do squats in the weight room. Squats work your complete lower body, and will help you develope curves. Not all men need . Plus, it sounds like you're very intelligent based on what you wrote. That counts for something. :)
