the moment friends start posting vague emotional messages or TMI on Facebook or other mediums, I lose all respect for them and I no longer consider them actual friends. Real friends communicate when there is a problem and not that sort of childish garbage. It's one thing to say "I need help." It's another to say things like "well, I guess no one likes me" or "here I am alone again" or "my friends let me down today"... it's immature and off putting. Bottom line, friends aren't mind readers, if you are upset, you need to talk to them.
