Don't worry too hard about it! I am keeping one of my closest friends who is extremely understanding no matter how he or I feels; I am cutting contact with a few others because genuinly we are too unstable for one another. I have done some shitty things, they have done some shitty things, bla bla bla. I am sure if I keep contact it will be an endless cycle of "I hate you so much" to "I love you :) /p"
Plus one of them is kind of??? Awful. She is a shitty person and makes me feel shit over stuff I can barely control (usage of drugs, my reactions to stuff, not being a religious perfect kid, etc etc). I would rather keep friends who I have a good relationship with (the guy who I mentioned earlier) than to be friends with people who have treated me like utter garbage :^))
Plus, the majority of my friends hardly pay attention to me ;;;; so that is another part that makes me feel shitty.
