I have a lot of acquaintances as well although I feel as though it's partially my fault. The only times I have really made an effort to befriend someone was after they were excited to talk to me first. After some recent bullying I've really just been keeping my head down but loneliness for me is the most unbearable thing so I've been trying to invite people to hang out and watch movies, or make food, or just go out and eat after a day of hard work. It's difficult to be the one who puts themselves out first but I've started to make a few more friends because of it. Don't give up You can do it!

Best of luck!
