Whats going on with me?

Im very outgoing and am usually only at home if there's nothing else to do lol but lately I've been coming home and want to go straight to my room and sleep. I avoid making plans and only go out if it's essential. I used to hate being alone and now i crave it. When someone comes to visit, I'm counting the minutes until they leave. When forced into social situations i talk a lot less than before and don't really care much to mingle. This is so not me. Has anyone ever expirienced this? Whats happening?
