What an ugly situation! I'm so disgusted with the professionals for minimizing your experience. It just shows that not every therapist and psychiatrist is qualified to treat abuse survivors.
I agree with Q. L that getting out of that house is the first priority, before considering taking him to court or even getting therapy again. Please don't minimize your mother's emotional abuse; it's also very serious!
Do you have family or friends you could stay with? Perhaps they could let you stay without charging you rent until you find a job. Keep looking for one because that's the first step to independence.
I don't want to minimize the suggestions others have made about getting help from agencies and professionals, but it does depend on the resources in your area. Some are excellent and some suck. You might want to check into child abuse/sexual abuse/sexual assault resources in your local area, even if they're geared towards kids. They may not be able to help you directly, but they might know of places or people that can.
Outside help is wonderful if you can get it, but you can't always get it. Please know that although the situation may feel hopeless right now, it's never hopeless. There is always a solution. Right now, a job and alternative living arrangements seem like the first step. You never know what might turn up when you least expect it!
