And so on.. Really? What is the worst that can happen? The people will tease you? They won't when they know how amazing you are. Become self aware. Target these thoughts and get rid of them. Fill that space in your mind with positive thoughts. Here is an activity which you might have heard many times ; but still it is worth it.
Achievement jar
Take a jar.
Everyday at night take a good thing that has happened today and write it on a chit.
Fold it and put it in the jar.
Whenever you feel depressed,just think about hose good moments.

I'm sure this will help.
