Still trying - Not very well

[limbo]

So it looks like we could be moving into crisis mode!

H told me yesterday that for the last few weeks he spends hours a day thinking about killing himself.
Early this last week he had a project pretty much taken from him, it had nothing to do with the job that he had done, it was totally office politics, but he has been working on this for the last 10 months, and has really worked hard on it, and I think this has kind of put him over the edge.
Needless to say I am full of emotions, I am scared, worried! And the selfish side of me thinks I can't do this again! I feel like now I am almost waiting for someone to show up and tell me he is gone, I can't be with him every minute of everyday! Thankfully he is back with a C, but has not told her how he is feeling.
I tried to talk to him yesterday telling him how well he has been doing, and he himself admits he has long stretches of really good days.
I don't want to sound flipant or cold because I am not, I am just not sure what to do.
