ok i am sorry your mother is sick, but you are an adult and can not take care of your parents your whole life you need to move out get a job live with friends because if you stay with them they will control your life forever don't let them guilt trip you in to doing things there way if you are not happy go get happy leave you will feel so much better leave them a letter explaining to them how you feel maybe they will understand
