Bipolar Disorder Support Group
Bipolar disorder is not just a single disorder, but a category of mood disorders marked by periods of abnormally high energy and euphoria, often accompanied by bouts of clinical depression. This is the place to talk about your experience with bipolar disorder, learn from others' experiences, and find support.
I suggest going to a counselor or talking to a professional for advice. You may not even have to do an inpatient program. But if you do, your brother can stay with a relative or one of his friends' families. There's always a way and if you need help, don't ignore what your mind and body are saying to you. Trust yourself to do what's best for both yourself and your brother. Best of luck to you, and if you need to talk I'm here, and I can lend my advice and experience to you. Hang in there!
