We have grief support groups here, I'm sure there is one near you as well.
Sally, you won't know what's left in life for you until you try for yourself.
Will detox take you back ?? Ask your Dr. to get you back in AND STAY THIS TIME.
If you are going to die of Asthma, die on the detox floor and not in your bedroom in self-pity. That's the decision I had to make in '89 when I was having the anxiety attacks in rehab.

All the best.
