Grown and was slapped across the face by mother?

Truly your mom was out of line.I just think that if she wasn't complaining about the blouse it would have been something else. She just needed an excuse to lash out at you that's all. Her problems is probably much deeper. I know how awful it is to live in a home with tension. The best thing for you to do is give your mom some space and this will give her time to think about what she did to you. If she has a conscience she will feel bad about it and want to talk about it. If after you have given her time to think about it and she still has not come to you. Go to her and apologize about the blouse and after that, I would suggest you move out and keep your distance until she grows up.
