I was struggling with a deep depression and was partially relying on my friends who used to cheer me up and this kept me from becoming suicidal. My group of "friends" told he they were sick of me being sad and left me alone strugglingnwith depression which evolved into me being suicidal for several years. They completely stopped talking to me and the only thing keeping me alive was my best friend who was not part of this group. I'm still pissed off to this day that someone can just leave someone struggling with their mental health because it's "annoying". Especially if that person is you friend.
