I can no longer tell which is the truth

I don't know, I don't know why. Maybe you really is that open-minded and still can act like nothing happen. Maybe you need my help, that's why you still so good to me. I don't know and really don't want to think of it. I feel so uneasy when you leave me by myself and do your own thing. I feel so happy when you call or text me and ask me questions. But don't only come to me when you need my help. I really don't know what I am to you. A life buoy?
