The problem with marijuana, from what I've read here about those who've tried to give
it up, is that it is sold now in a much more highly addictive form and is very difficult to break
the addiction. Before that happens, I would help her wean from it and look for other,
more healthy ways to control the feelings. "The Lemon thing" is one that is helpful.

It might even be helpful to try acupuncture.

Your husband must learn to realize that if she is bipolar (and you need to have that
checked with a psychiatrist) she may need medications to keep the illness from growing
worse over the years. That can happen if she remains without medications for a long period.

Please ask that your husband attend the psychiatric conference, as well, to learn more
about treatment and improving feeling tone for your daughter.

She might not be bipolar; that would be wonderful, but you cannot risk not knowing.
Either way, a psychiatric conference is called for, in my view.
