I've known 3.
One of my dads best mates rode his motorbike into the front of a bus , apparently it was very messy.
2 blokes on my post round who I knew quite well , the first hung himself after losing his job and getting into debt and was found hanged by his wife and 2 small children when they came in from school , the second was in a bad place mentally and had severe back pains after an accident (registered disabled) and after a bit of a bust up with his wife took an OD of his painkillers.Both of them had/have gorgeous familys.
I feel so lucky to be part of a loving family , my wife and son mean everything to me and more than make up for any shortcomings in my job or occasional financial problems.
