feeling empty

I am feeling empty tonight.  I am tired from dealing with my boys all day and then tomorrow,  we are going to race school so that my dh can learn to drive a race car.  The boys and I will be sitting around for 2 hours while he is in the classroom and then as he does 75 laps.  We always have time and money for what he wants,  but never what I want.  He keeps saying that I don't have to go if I don't want to,  but I know that is not true. I really don't know exactly what I feel right now.  I know that I can't wait for Monday,  so I can go back to work.  I do not like Sunday's because it is family day.  It usually means yelling and fighting with the kids.  no fun
