feeling down

    I don't know what it is but I just have been feeling down.  I have been snappy towards my family (mostly toward my finacee).  I feel like not happy by anything that used to make me happy.  It has caused me to have writers block from a story that I have been working hard on.  I try to do things that make me happy most of the time but it just is not working.  I'm wondering if I should go see someone or just wait and see if it passes.  I just want to be back to my old self again.
