I don't want to be me today

Ahhhh... I just didn't have the world's greatest day. I didn't realize that until the drive home when I added it all up. It wasn't work - it was the people who work for me. It didn't go well. I just drove home doubting me and the choices that I made, the way things came out of my mouth, how things happened, what happened, and my temper. I've had a really short fuse lately. I think why I am mad is okay - but oh my lanta it does not come out well. I get so angry! and frustrated! I hate having to tell someone something everyday and they think that I am the one with the problem. Today was one of those days and I just left thinking why do I do this? why do I care? Is what I am trying to accomplish really worth all this? At the end of the day, am I proud of who I was?
