My prayers go out to you, Cullen and his family. It is so hard. I just went through (ongoing process) with my daughter. Suicide is becoming a huge problem with our young people. They do not have to be depressed. The part of their brain which deals with long term decisions isn’t fully developed until the age of 24. A speed bump in life can sometimes cause them to make an impulsive decision.
Be there for your friend he will need all the love you can give. We can’t always know way things work out the way they do. “Life is cruel God is not”
I am sure he will have lots of support, but if he would like to talk with me when he is ready feel free to contact me. I am no expert just another father with a broken heart.
