I have dealt with BP disorder my entire life (not myself, but my brother). It was not easy at all to deal with, especially considering I am the younger brother. One moment he could be fine and the next threatening his own life. We had to deal with many attempted suicides and other various threats. It was extremely difficult. Especially with me being so young at the time, it was extremely scary and hard to understand.
He was in and out of hospitals, saw many mental health doctors regularly and has taken many medications to control his depression. It took many, many years of medicine "cocktails" variations to get something that has worked well for him.
He currently is 31 years old and doing extremely well. I would say the past 5-7 years have been *really* good. He has found a great job, house, relationship and good friends. He has his moments still, but nothing like it used to be like growing up. It is a significant change to what we had gone through. My parents really did everything and anything they could do for him for so many years, and it often wasn't enough for him to be OK. It is very difficult to treat/control mental illness.
It is wild though... In my brothers case, he was perfectly fine up until a head incident he had riding a bike. He slipped off a bike, hit his head hard and went into a coma. After that is when the depression and BP disorder started. All the doctors had said it was likely the head trauma likely caused it.
I am just thankful today that he is doing so well. A completely different person, really. He always takes his meds and all has been well.
It is unfortunate that Robin Williams could not find the proper help... Mental illnesses is no joke, and too bad he could not get the proper help he needed. He will be missed by many, that is for sure. It is just crazy that someone with the money and resources he had available to him, he could not get the help he needed. I guess in some cases, you can't be "fixed".
