WHY?!

I was apparently getting multiple messages from family for the past few days only to know that I was signed out of skype for some reason. I mean come on. At least let me try to identify which account I am because I dont know what my password and email is anymore. Why would the app just sign me out without my permission? This is ABSOLUTELY stupid and I want help getting my account back.
