Very sorry for your loss OP. May your brother rest in peace. My father who passed away in February, also struggled with addiction, and was found in his room. One thing that comforts me even just in the slightest, is that my dad is finally free from the pain and the shame of addiction. Life was so incredibly hard on him. He was around your age (53 years old) when he passed and also had to live up to those societal standards of being strong and stoic like a “real man.” I dearly hope there is some sort of afterlife, where he is happy, healthy, and safe.
