Welcome to SR!!
Some of the more common ones used here are
A = addict/alcoholic
AH = addict/alcoholic husband
XAH = ex addict/alcoholic husband
AS = addict/alcoholic son
AD = addict/alcoholic daughter
XABF = ex addict/alcoholic boyfriend
DD = dear daughter
DS = dear son
RAH, RAS, RAD, etc = recovering addict/alcoholic husband, son, daughter
There are probably more, but that's all I can think of right now.
Oh, and OT in a title of a thread means Off Topic - took me a while to figure THAT one out
Hugs and prayers!
