@sarahsweets: Yes i meant manic. It seems every episode is mania , like unipolar mania.
I know it must have been so tough for you, to see your daughter go through such tough times and you cannot do much about it.

But i see your point, it is so difficult to accept and think like that and feels scary.

Here are few things which come to mind :

1. To me it appears that, many people with mental health issue don't feel that there is anything wrong with them and instead other people are wrong. Why will they ever take help or ask for it? Instead they would want to correct others.
Will approach you suggested [that let me go through consequences of their actions] work in such scenarios ?

2. I also feel at times, people who don't want help and keep suffering. Should they be left on their own. It presents such a tough scenario.
