Self-Confidence.

I wish I believed in myself more. I get straight A's but yet I don't think I'm smart. I'm a size 4 but I think I'm fat. I'm short and I want to be tall. I have a great boyfriend yet I am always thinking he doesn't love me..or why should he love me? He is getting sick of my crap. I don't know what to do. I need to change. I feel so unhappy. It has been a tough year on me and as it comes to and end I just feel it all on me..pulling me down.
