I'm very sorry for your loss. A friend of mine that I knew since I was about 10 years old chose this last year. From what I was told he had recently received a very bad medical diagnosis (not sure what it was) and he chose to go out on his terms. I wish he hadn't made that choice, but I wasn't there and I don't know what all he was going through, so I can't judge him for the choice.I just found out my best buddy, a cop I've worked with for over 30 years, just blew his brains out. I've got a gazillion things going on in my head right now.
Y'all pray for me.
I still think about him all the time and wish I had a chance to at least talk to him one more time. He was a great guy and helped form my personality (for better or worse) from a young age. He ALWAYS seemed to be in a good mood, but that just goes to show that you never know what someone is going through.
Just try your best to remember the good things about your friend.
