There is this girl I have known since August and she is just great. I talk to her mostly in class but I think I am in love for the first time. I have never felt like this about a girl before and it isn't that I want her its that I feel I need her. I normally can talk to girls no problem but I'm scared to ask her out because I don't want to say the wrong thing and lose her. I'm literally in physical pain and have feelings of happiness and sadness at the same time. I can't stop thinking about her, what should I do?
