Not a personal assistant

Now anyone who knows me, knows I have alot going on right now. The baby stays sick and this whole job situation is killing me. Why all of a sudden have I become a personal assistant? So it is time to shut it down. I'm not giving rides, information,making calls, nothing. If it specifically has nothing to do with me and the kids I am done. I don't have a problem helping folks, but when you tell someone you need time for yourself they have no respect. I need a moment to concentrate on self. There is a reason I am not in a relationship. All I have to concentrate on is me and the kids. Thanks for letting me rant.
