Now that this is all over, I'd like to congratulate you both for your attempts to overcome diversities (for lack of a better word).
I have had family and close friend experiences with a wide variety of relatively similar problems (alcohol, drugs, and mental health issues) which have ended in early death or suicide even when I did my damn-est best to intercede.
Illnesses such as this always have an adverse and long term affect on just about everyone associated with that friend or loved one who has a problem that is almost impossible to overcome.
God bless you both and never give up. I think I am saying this on behalf of the majority of GetBiggers here.
At least, I hope I am.
