Learn how to KNIT:-) I taught myself three months ago and it is saving my sobriety. Find something to do ANYTHING, crochet, gardening, or ANYTHING that will keep your mind occupied. Many of the same lessons that apply to those of us in recovery ALSO apply to "this side." Shift your focus in life from what he is doing or NOT doing and on to YOURSELF. Its the hardest thing in the world to do, takes time and practice but do it. If you need to go to three Al-Anon meetings a week and find their online chats go do them. In the past month I've had both in-laws in hospitals and quite frankly I couldn't afford to relapse. I kept screwing up my new knitting hobby but while I was knitting my mind was focussed somewhere else. I also got my rear end on my sobriety groups online nightly chat meetings which I COULD do with an elementary aged daughter while Daddy was at hospitals. I finally found a path out of inertia and this is the challenge you too face.
Peace. This stuff is hard but you CAN do it.
