Yes, I have come to the conclusion I have social phobia. I can sometimes do OK with people, but inside, I'm not as comfortable as I wish I could be. I suppose I am afraid of being preyed upon, because I am way too trusting of a person and get taken advantage of so easily. I'm not sure if I have truly found people I can not worry about chipping away more of my already very low self-esteem. I am a very giving person, would give the shirt off my back to anyone who needs it, but I always seem to get taken advantage of, then when I get up the courage to say no to people, I end up being the bad guy, no matter all the good deeds I have done prior, those seem to not be remembered nor recognized. Then, I get punished, then I in turn punish myself. Its a terrible cycle.
So, no you are not alone.
