Why so sad?

Today has been one of those days where I just want to listen to sad songs and watch sappy girly movies so I can cry the whole time. Not real sure what is going on, must have not gotten enough sleep last night and it was a hard day at work... Things aren't that great right now in the marriage but both of my kids are healthy and happy.. K guess I complained enough, time to suck it up and get in a better mood!!!!!
