Surrounded but isolated

Ahahahahaha. I just love coming to social gatherings of all the people who are friends with her and tolerate me. I only have to go a few more hours and then I can go home and ignore everyone.
I'm already so done after she showed off her SO. Like, someone told a joke about her coming out of the closet, and she was all jokes on you I did. Like. Fuck her. I wish I had never become friends with her. I wish I had never met her. There are so many things that would be better in my life if I had never met her and made so many decisions based on her.
Ugh. I'm surrounded by so many people that I'm coming to realize I share almost no interests with. Besides the fact that we're all nerds, I have nothing in common with these people anymore.
I just feel completely ostracized among them, and it's probably my fault. I'm the one who ultimately thinks all of their hobbies are useless wastes of time. Roleplaying? Pathetic. Spending hours and hours watching all these shows? Do you ever work? Running cosplay blogs? That's just sad. Get a life. That's how I feel most of the time, which makes it so hard to pretend I care or care to keep up with what they're talking about.
Does this probably just make me a huge dick? Yeah, if I'm being honest. Do I have no friends? Pretty much. It's almost impossible to have friends when your life is controlled by a social parasite.
