I am 17 years old and i have been best friends with this girl since we were more or less born always hung around each other we have always been close and we always do things we each other. But i have started to develop these feelings for her and i don't know how to tell her i am scared of getting rejected. I can't stand not being around her and i hate it when guys flirt with her at school and i just feel so attached to her. I don't know what to do. Should i tell her about these feelings? Am i in love? I feel like i am but then again i am not sure. Advice?
