Yes your life is important! Perhaps you could seek some help with a family therapist develop a plan for your son to move him out of the house. Even though he is mentally ill he is still responsible for his own life. My daughter is bipolar and alcoholic/substance abuser. There is no way I'd let her live with me. My own sanity would be at stake. I read a book called "don't let your kids kill you." Sounds drastic, but living under such constant stressful conditions can be a danger to your health and even your life.
