Suicide is not funny. At all. It is beyond insensitive to joke about it, particularly when you know that two of the four people you are with have seriously contemplated committing it, and the other two are 11 year old boys.
When someone tells you the obvious, that they are in a deep depression, the proper response is not to say, “well who isn’t,” with maximum venom and sarcasm. Nor is it to detail the ways that you have tried to help. THIS IS NOT ABOUT YOU!
I am floundering. I am scared. I am alone. It is very dark in my head.
