DoubleBarrel,
Sorry I didn't pick up on this thread earlier.
I am going through something similar in my own life.
I have been free of my addiction for a long time now so the thought of drinking over the situation has not been a problem. But there was a time when it would have, and although I am not currently considering numbing my pain through alcohol, I find myself wanting SOME form of escape...not all the time, just some of the time, long enough for me to gather my strength for further onslaughts.
What helps me is to make sure I get enough sleep (that is an easy thing to forget!), some moderate exercise, and take some time every day for myself (even if it's not a long time).
I also try to remember that in many ways it is an honor to be able to support someone in their time of need. When I was addicted I would not have been able to do this. I would have run like the wind....but now I am able to do what needs to be done.
