@suhailfanous It is indeed heartbreaking to watch a friend or family member with mental illness. I am not sure what you mean by practical treatment.

Like any other mental health, and physical health for the matter, condition, each person is different. That is, what works for one person may or may not be the correct route for someone else. It is generally understood there is no "cure" for bipolar disorder, but there is treatment available. This treatment can include medications and therapies. And importantly, actually, most importantly, the person suffering has to be ready/willing/able to address the issue and actively participate in the treatment.
