I'm so sorry that you are in this position. You are staying for a month? Maybe you can eventually visualize yourself responding in a different manner to your mom in a few days or weeks (as opposed to hiding and doing what you are told)? You can still do what she needs done but from a position of that it is what you need to do to help your mom and not from the position that if you don't do it that she will get mad at you and hate you.
