<human>: Can you condense the text into a few key points?

I'm a senior in high school, and throughout the first three years I had plenty of friends and I liked them/ made plans with them, but I've gradually lost all desire to have anything to do with them. In the last few months, I've had blowout end-of-friendship fights with three separate close friends because I never want to skype/ talk on the phone/ hang out. But I really just do not want to, to the point that I dread holding plans that used to be fun. It just feels like there's always someone who is demanding my time and it's stressful. Everyone seems to be so self-centered or immature or insert-character-flaw-here too, and it worries me that I'm so quick to find the flaws in people and be bored of them. I don't think I genuinely like more than one or two people anymore, and I even struggle to want to talk to them most of the time.  
I did have a boyfriend who I wanted to see/ talk to as much as humanly possible, to an unhealthy extent. I think I might have used him as a form of escapism(?). I'm also worried that I'm wired to only value romantic relationships. But that's ended which has effectively reduced the number of people in my life I like by 50%, and I'm just worried I'll never really like anyone again. I feel guilty for disappointing all of these people and I feel bad about myself for not having any friends anymore, but I don't really feel lonely or isolated even if I go days without talking to anyone.
<bot>: Hate hanging/ talking with everyone in my life but I want to have a social life. What's wrong with me?
