Recently I've noticed that I've been isolating myself from people. The only people I will be completely willing to hang out with are my three closest friends. A few weeks ago I had a falling out with one of my main groups of friends and I decided to forget about them and focus on other people, but whenever I'm bored and trying to find something to do, I think of people to hang out with, then I kind of convince myself not to contact them for some reason. It's like I tell myself it won't be fun or something. The only thing I have felt like doing is being in larger groups (like parties) to minimize one-on-one contact I guess. Am I going through withdrawals of hanging out with my old group of friends or what? I don't understand why I'm avoiding hanging out with people because I've actually been quite bored and lonely whenever my three closest friends are busy at work/school etc.
