If she stays on her meds, things should be not too bad. But sometimes things get out of control and you will find yourself in a tight spot. I've known some to become quite violent, others are the opposite, when the are manic they go way ou on a limb for everything. Very hard to deal with sometimes, but the best you can do is be there when she needs a shoulder or an ear. And if things are said that makes you feel resentful, remember, it's mostly aimed at herself, not you. If they can stabilize her with the right meds, things should go smoother for everyone involved.
