No matter how hard I try or how stupid it seems I can't stop being jealous of my friends being friends with other people. It just makes me so so sad and triggers me and makes me want to split and push them away. Its like I'm replaceable or not good enough for them. Especially when they do things together without me. I know it sounds selfish, I'm so aware of how stupid my thinking is. But I still can't stop myself from feeling this way no matter how hard I try. What is wrong with me?
