care plan bipolar disorder

How to tell a parent goes out?
I am 20 and have decided to leave because a lot of family issues. I basically take care of the house, cook, clean, do laundry, all without help, and my relationship with my mother and my brother is very tense. I was diagnosed with bipolar disorder on last year, and I feel that to improve, and with the recommendation of my therapist who should leave the toxic situation. What should I do to tell my Mom plans to leave? Even my therapist said I should go without saying anything … but I feel like it would be a terrible thing.
I would like to address the subject delicately. When members of your family are in a quiet, calm I would be happy to mention that is twenty years and I have been thinking about the growing thing and be fully accountable and on their own. I would not go to all the information about your therapist's suggestion or any work to do there, etc, which only open arguments and more problems. Have the states, not blame or accusations. Let them know of their plans, as if you have a job or work of creation, a possible place to go, etc, see how they react. If they start to react in anger, only to fall and then go ahead, do not let them get in a fight over he. Just to let you know, state what is going to do, and do. Then you must know, and not place blame or more pain in a situation of already intense and you will be free to move on their own. You might not like. ODD is unfortunately going to react to the news. But stick to your plan if one is right for you. Good luck!
