i think you should be kinder to yourself. Your human and even if you hate food, you still need to eat for energy and life. start telling yourself good things like: Im smart and nice enough that i will make a great friend. sometimes its other people who hurt us... not that your hurting them. you did enjoy your conversation with this girl which means your capable of socializing..you just need to build your self esteem. ...self affirmations may help. believe in your own beauty........not what the world says.....hope this helps..
