My flatmate of 3 years has become addicted to cocaine and is drinking more heavily than ever before. I used to love hanging out with him and living with him used to be the best but now it feels like I’m walking on eggshells and I’m the one always trying to save our friendship and putting in an effort. He falls behind on rent and I’ve began to feel like I’m being taken advantage of. I don’t know what to do cause usually I love living with him but it feels like it’s irreversible now. At the same time though I don’t want to live by myself during pandemic because I’ll just be all alone. He caused a big argument about 2 months back saying hurtful things and I started to self harm cause I felt so bad. I don’t know what to do, he’s my best friend and has been through so much this year but I don’t know what to do I feel too dependent
