A few months ago, I lost a lot of my friends over an argument which I ended up being right about. The details of what happened isn’t important. Looking back on them, they were kind of jerks. My sister, whose also in the friend group, told me that one of them never liked me anyways and the group is falling apart. Even though they were jerks and it’s been months, I still can’t help but care about them. I think I care too much about what others think about me. I don’t know how to stop. I can’t help but feel terrible as if it was all my fault, even though it’s not. How do I just shrug these people off and forget about them?
