Hi, Brain,

Money solves part of the problem for right now.
If someone hired a lawyer for her, she could get diagnosed for the jail's purposes and get on meds.
She would still be legally able to refuse the medications as that as her right even in jail for DUIs -- unless she is judged incompetent.
But lots of money helps some of the problems you are talking about.

OR -- look at this --- there is a degree of luck (or fate as you have it) in getting better.

Her jail might be relatively free of corruption to the degree that she has no access to alcohol or drugs while she is inside and so gets clean.
Then a profesional (or her by herself) decides she needs medical help.

As Waves says, she could have more than one diagnosis and might not be bipolar at all.

Getting clean in jail is a first step for good things for her.
