I know what you are going though, we have gone through this a few times with our 31 year old son who has had bipolar disorder since he was 21 and in college. We think weed and nicotine contributed to his breakdowns hospitalizations. He takes medication, which was adjusted and started up therapy again. To answer your question, he had to move in with us each time in order to recover. This time he had to move out of state to live with us. Each time it was hard, including this time, but he is getting back on his feet now after 6 months, has a job and is saving money for a car and to move out on his own again. If he had stayed on his own, I don’t think he would have survived, or would be on the streets or in jail as he was out of control. We had no choice as parents we felt. So, yes, I think he needs you in order to get better. Is there a way he can move in with you instead of the other way around? That way you don’t have to completely rearrange your life to move there. Although it is still hard having a grown adult child move in with you! Best of luck to you, sending prayers your way, it is a difficult time I know!
