frustration

Ok so I know that in a perfect world everyone would constantly be overjoyed when spending time with their kids.  Today has been one of those days and I can directly relate my frustration to the fact that my mind has not been right lately.  I hate the spritual rollercoaster that I am on right now.  One week I am up, the next week I am down.  It is the "down" time that I struggle with.  Any negative thought that I can think creeps into my mind.  I lose patience and just want to get away from everything.  The thing is, I know how to correct this ship and start getting back on the up side.  It is the ability to man up and turn this thing around that I struggle with.  I love my life, I love my family, and I love who I am (most of the time). But the past few days I have been struggling.  Time to man up.
