Nothing you have described is jumping out at me as being particularly characteristic of bipolar. Mental health or possible addiction issues, yeah, probably. And I agree that what is probably most important is getting her to find some kind of treatment.

But what you are describing could be any number of things, post traumatic stress disorder and it's many different faces could also account for the kind of dramatic changes in attitude, priorities, etc.

I think that for people outside of it, the upswings of bipolar are usually a lot more out-of-nowhere alarming, like: "why is the house suddenly full of rescue animals?", in that state we are moving at the speed of light and from what I can tell the normal outsider reaction is usually more "WHAT just happened!?!" than a gradual "...maybe something isn't right here"
