I'm really sorry to hear that - truly.
I can relate. I lost a bother many years ago. He was 25, I was 24 at the time.
Drugs? Yes and no - He fell asleep smoking a joint and set the bed on fire.
Died from smoke inhalation.
Tragic.
My parents never got over it. They've both since passed away aswell.
I still don't like to overthink it. Buried somewhere in the too hard basket.
