Remodeling sucks!

I had this bright idea a few weeks ago to knock out a wall and in turn make an extra bedroom. We don't have the money to add the addition my house so desperatly needed but for $200 I figured lets make a temporary 2 year solution until we can build the addition. I guess my dreams were far fetched when I thought it would be a weekend project. 3 weeks later I still only have a shell. Every couple days the guy comes back to put on some new "mud" on the drywall but it still is not nearly what it needs to be. My house is a chaotic mess. Not only am I going crazy but the children are now getting frustrated because the toy room is gone and they have no where to play. Ugh! I still have to get the dry wall finished, sanded, the painted, carpeted, and oh lets not forget about the door, which he forgot to put in. Im about to take a sledge hammer and knock it all down and consider this a sour project! I have no patience, ok I have some but its worn thin at the moment. I NEED MY HOUSE BACK!
