Hmm, I'm just the opposite -- I have friends IRL, but everybody at PC hates me.
I guess I would ask what makes you think nobody likes you IRL. From what I know of you here, you're a very caring person with a good sense of humor. Are you more shy in person, or more doubtful of what you have to offer people? A lot of social interaction is "fake it till you make it." I'm disgustingly charming and witty and fun when I have to interview people for work, which is not at all how I see myself, but I put myself out there that way because it relaxes people and makes them more calm about talking to me.
I dunno. I don't really have any good answers for you, except to say I like you just fine.
Love, Candy
