that is exactly the same problem with me.. no joke :$ and its also you get in fights with your friends, you try everything to make them happy and keep being friends but when they do something that it is their fault, they just ignore/be mean/ and blame all the problems on you.
yeah, that's exactly how i feel. i'm so nice to everybody around me and i don't get anything in return. i help everybody and everyone dumps their problems on me and then i need that and nobody's there.
