Why Do I Upset People So?

Seems as of late that I cannot help but have the people closest to me upset/mad at me. No matter how much I care and try to express concern while giving freedom, I still seem to push people away. Maybe I just really have no idea how to treat people. Maybe I really the villianous monster that I feel I have become. I am at one of those stages that feels like everything I do in my relationships feels wrong. Like I am not saying the right words, doing the right actions, or at least waiting too long to do the right ones. Am I doomed to having no friends cause I am so unlikeable and the ones I have I mistreat so they run away? Am I destined to only liking girls that don't like me? Looks that way.
