I offer as many condolences to you as my internet connection can carry. Reading that you lost someone who was merely trying to take care of themselves really, really hurts.

I graduated high school in the mid 00's. When I last ran the numbers in 2018, my graduating class of ~250 had lost roughly 4% of its people over the years due to OD.

I deeply want this set of problems to get better, but I cannot convince myself that it will during my lifetime.
