Thanks, bluebicycle. It's mostly about stress, and likely also related to my mood state.

I'm sorry to read about your friend, bluebicycle. I fully understand how it feels to lose someone you care about to suicide. I also understand how a loved one could feel angry at doctors, or other health professionals, who are supposed to be the most qualified to help. Of course people make mistakes and of course sometimes as hard as they try it is not always enough, but sometimes such experts don't seem to have done enough. Anyway, it is a bit of a triggering subject for me, but I do feel for you and your friend's family very much. I also like to say that I feel for the person who lost their life to suicide. It is a tragedy for them no different, in my view, than losing life by other causes.
