Hey, I DID IT. I was very direct with her, and I reassured her I had absolutely no intention of follow through on these thoughts.

She was AWESOME about it -- her first words were "don't be afraid to tell me things like that, suicidal thoughts are normal, I'm not going to stick you in the hospital just because of that".

So, we're changing medications (again, alas, but that happens), and I told her I was going to make a real effort to try to concentrate on the positives in my life. She wants to check in via email or text message weekly, and I'll see her again in my regular 3 weeks.

I'm so relieved.
