Maybe answering questions again will be good for you, an opportunity to better rationalise and express your problems. That might help you to manage better or feel more in control, and to better express yourself to others, possibly lessening anxiety and frustration.

In my experience, that is how it can work.

BP-I or -II is not something you have to care about. As a general rule, more, longer severe depressions and mild mania may be indicative of BP-II, but there is no discontinuity between BP-I and BP-II.
