Hate A Friend

It was a long time ago. My friend and I, with one other friend were chatting and thank god the mic was on. My friend and her mum argued and we could hear it all. I was in it too. Scared that I’m on bad terms with my friends mum. Cant get over it. I cant even look or visit my friends mom without hiding behind someone. I also wanna get over of my friend randomly vanishing without telling me in the middle of us doing something digitally when we cant see or hear eachother. Im afraid that her (my friends) mom would argue with us again and my friend would get hurt. (No matter who it is) Its like, “please don’t disappear without telling me, it makes me scared.” Type of thing. Google doesnt help so I need to hear what you guys have to say.
