My friend, I can't even begin to name the people I've known who have died from either alcoholism or drugs.

There's just too many.
And why are you left? Because God still has a plan for you. Maybe you don't believe in God, but I do -- and I KNOW there's a plan for you. There is something you're supposed to do!! Maybe it's helping people here. Maybe it's helping people on the outside. Maybe it doesn't have anything to do with drugs/alcohol, but there's a plan.
You have a wonderful, bright life ahead of you! If ONLY you could see it! And it's NEVER too late to start.
I'm pulling for you. I'm with you 100%. God bless you. Hugs, Lee
