Some people just don’t get it

I’m tempted to stop communicating with most people for good; some of them are too sensitive and would want to attack me for something trivial. Then random people start to hold a grudge against me. But the same people probably wouldn’t be brave enough to admit to anything. Unfortunately, I know exactly who those people are, thanks to the fact that I don’t have quite as many friends, so they were easy to find. I’m not even going to mention them, because I hate mentioning their names. I always experienced them differently, as nice, but they turned out to be quite deceptive. People who seem perfectly normal turn on me without notice/warning, and that’s cause for concern. I’m concerned about what my future’s going to look like. I literally can't sleep at night because of this!
