Wraith wrote I get what you mean but what you have to remember is we are all human and we are all different. I was in a similar situation with a girl I liked, we are good friends but I realised she didn't like me the same way I liked her. I am completely fine with that as since we didn't have too much in common but I still like her as a friend now and we talk often.

If you really like this girl then the only way you will find out if she likes you back is either by confronting her about it, or waiting to see if you notice anything that indicates if she likes you or not (which isn't always easy). If you worry about the way you look, try to look for the positives in your appearance because looking at yourself in a negative way will only bring you down further. If it is an issue about your weight, you could always try improving your diet and getting more exercise but don't push yourself too hard because you will probably end up even worse.

Wraith wrote I mean if she knows how you feel then I think it's safe to say she doesn't have the same feelings for you although I'm not expert on woman so I might be wrong. I get some people worry about the way they look and I know how it feels because I used to be the same. It is hard to cross the barrier of not being worried about the way you look but you just have to tell yourself that it doesn't matter what other people think of your appearance. It is hard and it will take time but if someone really likes you then they will like you for you so don't go changing yourself to please others.
