I'm sorry that someone suggested that to you, and glad you won't be hearing that from someone here! Don't let it carry any weight at all, for obviously that is HIS issue, and not yours.
I don't think you need to hear that stuff...and hope you can have good responses no matter what site you are on (though I doubt you will receive the support you get here
)
I understand how people, such as yourself, that carry the suicidal ideation can easily be pushed over that line of no return. Remember, it was just a comment, really...just words. I think you could, later on, address why it affected you so...was there something other than the suicidal effort that struck home, do you think? But don't do this now, when you are so vulnerable.
Stick around PC more, at least till you feel comfortable in your own skin again, ok?
