If she's willing to see a psychiatrist, that might be a start. I'm not sure if it's OCD, BP, or something else.......perhaps a combination. There are varying degrees of MI and there's no pathology to it so it can be difficult to pin down. Much of what you say is reflective of how I behave - I have BP2 and tend to jump from one thing to another. BP folks are usually very creative and driven by challenges, but pursuant to the latter, we don't always stick to one thing because we constantly seek challenges to keep us moving.

The first step would be to get a diagnosis. Don't guess. Once you have the information, you have the power. You can start walking down the road of management and go from there. Keep in mind that it will probably never be cured, only managed. You might get an early fight from your daughter so be patient. It took me a few years of prodding from my family to seek help after YEARS of self-destructive behavior but I finally came around to in on my own without any ultimatums or threats.

Good luck.
