ev, I can't answer that for you. She may ask for a promise from you that if you begin to feel seriously suicidal and it's not alleviating, to tell her about it. I really can't say, though. She may just decide to check in with you once in a while on the thoughts.
I think one thing that will stand up to her is that even though you've had to deal with these thoughts so much, you're still there and seeing her.

I think that's going to speak volumes, you know?
Good luck and let us know what you decide?
