Also, be careful when you suggest she see a doctor. There's a delicate line between saying "I'm worried about you. I want to help. Let's get you some appointments and see what we can do to make things better," and saying, "This isn't working. You need to see a psychiatrist or something."
The first is an offer of assistance and a game plan. The second is blame and insults. Obviously, you want to aim for the first option!
It can be difficult to pay that much attention to your phrasing when you're in the middle of a very emotional discussion...but it's important, so really try hard.
