Don't feel like you're failing. Just be there for her and make sure she gets help if/when she needs it.

Thanks. I was tired last night and her talking about antidepressants pushed me over the edge, but I'm okay now

I've been on them for many years now. I kept trying to be off them & then I came to grips with the fact that my brain is just different.

I've been much happier since. It's OK to have to be on them as long as they make the person better.
