Challenged

I am feeling most challenged and overwhelmed by motherhood this morning.
I am tired of repeating myself over and over and over again.
I am tired to listening to them fight among themselves.
I am tired to endless requests.
I am tired of not being able to complete a task without interruption.
I am sick of complaints about everything....its never enough or fair enough.
Nothing is ever "right."  And I am just fed-up.
Even as I take a few minutes to gather my thoughts I am interrupted with a request.
And when I say I will do it in just a few moments I am being battered with the same request over and over.  I am trying to find peace in all this.  I know there is so much out there that is much more and much worse that what I am struggling with.  But I am in my world, with my realities, and boy it is tough for me right now.  My kids issues is just one of the things that I am trying to understand/process/deal with/accept.  Just looking for peace.
