Can you help me get to the bottom of this?

Basically, I am always really REALLY self conscious. Sometimes I have to cancel plans due to the fact that I feel ugly and that people look at me when I go out. Is this just typical girl behaviour (i.e. never satisfied with looks) or am I being stupid, or is this just true? https://twitter.com/katerinabacon/status...46/photo/1
Is it typical TEENAGE behaviour? im 13.

You are not being stupid trust me! I'm 13 turning 14 very soon and I have canceled tons if plans do to the fact I feel ugly or stupid etc... I hte people looking at me and I still do but I realized that I shouldn't care what people think and that being with friends always make me feel better! Don't cancel plans for those reasons! Trust me if you keep the plans you will feel so good about yourself! Everyone's gorgeous!

you are not being stupid. you are only 13, you have to accept yourself the way you are. and also your appearance will change as you are still so young. im 17 now, and i was the ugliest kid on earth - seriously im not joking! i was a fat midget real talk . now ive grown up and i look completely different as you can see on my pic. so dont worry everything will change as you are only 13
