So much to do and so little time

I feel like I am being pulled in a million directions.  We just moved into a house and we are trying to unpack in the few hours we have between work and taking care of kids.  We lived with my mother-in-law for a year so we are also trying to get everything else out of my mother-in-laws house so her daughter and her family can move in.  Then I have to clean her house.  Plus taking care of my three kids full time and his two on the weekends.  But I am bringing some of this on myself.  I had plans to do laundry tonight but of course I call some friends and invite them over for dinner.  I also have scheduled a pampered chef party for this weekend at my house.  Even with nothing really unpacked and decorated.  Am I crazy?  Why am I doing this to myself?  I really just need to focus this weekend and get all the unpacking done because I have a feeling I will have even less time to work on this next weekend since I will have all my kids.  As an extra bonus to my life, my ex-husband is moving about 5 miles away from me.  This will be great for the children since right now he doesn't get to see them often because he lives a little over an hour away.  Now he will be able to get them just about any time he wants to see them.  It isn't going to be bad for me though because my and my ex get a long for the most part.  I just can't stand the woman he is with because she was the one he left me for.  But thankfully we stay out of each others life and only talk when it comes to the kids.  I have it good that way.  But I have a feeling my over-jealous husband is going to have issues with this.  He already things that my ex wants me back and can't stand that we get along so well.  I just hope that everything works out.
