I have read your letter, and I decided to try to help you, if I can. I understand that your confidence is extremely low but are you sure that the plastic surgery can help you? It costs a lot of money, and it is very painful and uncomfortable for a while. Maybe, you should try to do some exercises which can help you to look better and it can build your confidence. On the internet, there are many web pages, which deal with physical training. Besides, you should find new friends, who don’t care with your look, and accept who you are. Some good and selfless friends can give confidence. If you think, that the surgery is essential you can do it, but you should consider whether is really necessary? I hope, you will be happy one way or another.
