I'm not even 40 yet and I have no friends. I've stopped trying and now feel worthless.

I'm not the poster child for making new friends. I've been a loner since childhood. At elementary school I had classmates, but I was never picked for anything, nor was I invited to birthday parties.<br><br>As a result, I almost always could be found solo. I had a best friend for a few years when I was 12. She even invited me to her 17th birthday party.<br><br>Sorry to cut the small talk with the story. It's pretty sad and lonely, I know that. I've also talked to a therapist about it. It didn't help. I've had classes and training. I've tried to join clubs, but I haven't found any. Nothing. I've tried. I've also talked to someone about how to open up a conversation with someone, even strangers. Again, none of it has worked.<br><br>I stopped trying a few years ago. I don't expect it to happen anymore. I am a real loner and not because I like it. It's just that I have no one. I'm 37 and no one cares about me. It feels kind of worthless when I watch other people's relationships and friendships and I can't even imagine going out to dinner with friends.<br><br>What's wrong with me? I have an idea, but I'd like to know why I'm so worthless to everyone.
