I just wanted to point out a couple things in your thinking process that I used to think myself, only to later realize my thinking process was flawed. First of all, you say nobody has ever pursued you. Is it possible that if people had pursued you in the past, you might have downplayed it because you figured nobody would want you or that if it was real, they'd make it more obvious (and then they took your lack of response to mean disinterest)? Just a thought.

Also--you are upset because those close to you don't offer to help. I still struggle with this one myself, but I know that people can care and still not recognize they should offer help. There have been times I have been quite visibly upset and nobody seemed to care, and when I finally got to the point of blowing up about it, everyone seemed surprised and wanted to know why I never asked for help if I needed it. Even though I thought it was obvious, if you don't say the words, people aren't necessarily reading your mind--or your actions. I'll bet people care more about you than you realize.
