I don't like clingy people in the first place, but I hate it more when that clingy person is also a fake friend who treats me as a back up friend. There is a person at my school who does this, if she is at loose ends, she gets very clingy and desperate and gets mad if I refuse to be with her. But if she is with others, I literally don't exist, she'll even look at me like she has no idea whatsoever who I am. Sick of it. Need to get these people out of my life since there are a few people like this.
