I read another post you made on a different website, but I forget which website. First, my deepest condolences for you loss. Second, your story is extremely similar to the story of one of my closest friends. In the wee early hours of 12/30/2007 (Sunday) he committed suicide by the same means your husband did, but in the family's basement. He is survived by his wife and two beautiful children, both under the age of five. It was a complete and total suprise. He, like your husband, is also from another country. My friend is right now with struggling to get past immigration issues so his family can receive emergency visas to attend the funeral (she did not release his body to his family of origin).
It is just so weird, when I started to read your post I really thought my friend had written it.
Anyway, just wanted to let you know that there is someone else out there dealing with a very similar, and equally apalling, tragic, and sad situation. Maybe you two will find each other on one of the message boards. I don't think she does much on-line, but in the coming months she will probably start to.
Again, my deepest sympathies.
