Take a break. Playing guitar, like any art, is about expression. If you're having a hard time with it right now, put it down and find something else to do for a while. Personally, I haven't played much at all in the past month, because I've been going through a lot off stuff with some friends of mine...Teenage drama tends to keep a person busy.
But yeah, try to pick it back up in a little while, and see what happens after you've given yourself time to refresh your thoughts.
