I'm thinking of ghosting my depressed friend.
Why would you ghost them?
She kept on complaining about me and blaming me and it got to be too much.
I know it can be difficult dealing with someone who is feeling depressed, but your friend needs your help and support. It's very rude to just disappear on your friend, especially since they are depressed. If you abandon them, they may spiral down even worse and even contemplate suicide.
I don't care if she tries to kill herself; it's not like she would succeed. I just want to delete her off my fb and never see her again.
I am sorry that you are having a hard time dealing with your friend's depression but disappearing will not help. She might get worried and try to seek you out. It is better to end things on a good note so that there are no unanswered questions.
