I agree with MM that you need a therapist. Your mother may very well recover sooner, rather than later. Medications can help quickly in some cases. But all cases are unique. When your mom is well, you can work on a plan with her. Some conditions she must meet before hospitalization is needed. This can avoid any problems of blame in future episodes. She must become part of her own treatment and you can either choose to be a part of her support system, or let her know you cannot deal with it. You have both options. Please take care of yourself through this.
