Ahhhhhh

I am at a point where I am feeling very overwhelmed. I have taken on an extra class, I am already falling behind in all 3 somehow, even though I have always been able to stay ahead in my last 3 terms. My house is a disaster, the kids have been acting up. we will most likely be moving to another house at the end of March. Not to mention some other personal issues. I feel like I have no control right now. I can't concentrate on anything. I try to do my schoolwork and I just can't seem to focus. It's like my brain has just decided to shut down. If anyone has any advice, I would greatly appreciate it.
