The pie is really messed up...

For the first time in my life, I am having somebody expressing interest towards me. And by interest, I mean actually liking me for me. I'm not sure how to feel as this is the first time this has ever happened. I'm so used to pouring my heart out to somebody and having them do nothing in response. This feels pretty weird cos for once, it's not me who's being all romantic. I'm not sure what to make of it though. I really do care about this guy alot and I think he is an amazing person. I know that I mean the absolute world to him but I'm just so not used to having somebody care about me so much. It feels so strange. I'm not sure if I'm ready for a relationship because every time I think about it, I start to feel nauseous and all my previous relationship failures come back to me. I don't know if I truely know what love is or how to express it or if I'm just too deeply emotionally scarred to even accept it at this point in my life. I'm so scared and worried that something bad is going to happen even though it probably is not. I almost feel as if I don't deserve to be treated so nicely...fuck what is wrong with me? *goes off into the corner and sobs*
