What is up?

I am so damn emotional lately, I cry at the drop of a hat! It's really starting to bother me, it gets so that I can't function during the day. I mean some of the stuff is understandable - this morning when I heard they had found the body of that 11 year old Florida girl - I just bawled. UNDERSTANDABLE, that is such a tragedy. I can't stop thinking of her and her parents. But there are other things that make me cry - that I just don't get...I mean, I'm getting weird. I'll cry at commercials, songs, just plain weird things that I shouldn't be crying over. Why am I like that?
