I've read a lot of strong feelings here; HB of course is right -- suicide is never the answer.
I can't say I've felt suicidal, although when the pain was at its worst I do remember just wanting to go to sleep and not wake up -- but by that I didn't mean never, I just wanted the oblivion for a while. I think we've all felt that way. It is the exhaustion and stress talking.
One of my H's good friends -- godfather to one of our sons, even -- committed suicide what is now 6 years ago. That was the start of this whole mess for us, as I've written before.
We saw him more in the last year of his life than we had for ages; in retrospect he was saying his goodbyes. The last Christmas he made us a wonderful CD in place of a card; he said he was doing that for his friends that year. He helped me clean and decorate the house that year. He was happy and fun with the kids.
NEVER did he talk of feeling down, of anything that might have given a clue. He did NONE of the things on that list -- maybe making those CDs qualifies. I suppose looking back there was a certain cynicism about life, but that is all. Yes, he had had the setbacks, to do with work, and I think he hurt badly when his dog died. But so much else was going well -- he had a girlfriend for the first time in years and was happy in that relationship. Turns out that wasn't enough.
He hid it well. Turns out that he had probably planned this for when he ran out of money (I won't go into the story); the morning he died he sent an e-mail to H saying that "they finally turned my phone off, oops".... and then said he was thinking of us. Didn't say what he had planned, though -- we found out 2 days later.
I've heard professionals say that those who are serious don't talk, and that was the case here. They also say that when someone has made up his/her mind in this way they often become calm and even happy, because they see a way out of their pain. And they also say that it's not possible for anyone else to change their mind.
I often darkly joke that if he weren't dead I'd kill him for what he did. And it's not funny. Not only was the suicide selfish in and of itself, but sending that last e-mail laid a huge guilt trip on H, which, combined with all the other guilt and resentment he was feeling started the process which ended up like this. And that's just us; we weren't even close family. What it did to them doesn't bear thinking about.
A few months after BD my H had said that he had stood on a train platform, wondering what on earth he was even doing here (meaning in life), but thankfully that went no further. I did tell him then that as much as I hurt from his leaving that I was glad he did that rather than do like his friend did.
Us LBS often express the sentiment that a bereavement would be easier to deal with than the MLC; I've felt that myself, but I do NOT think that applies to bereavement by suicide -- that would be like MLC compounded. An accident or illness isn't rejection, it's what happens. Suicide is deliberate, and is the ultimate rejection.
It is always worth it to keep going, for ourselves and for our children.
V -- I was just writing this as you were. That was very brave to share; this is such a difficult topic.
