Just look at it this way. Out of the last 46 days you only drank on one of them. Also, consider apologizing to your daughter if you think you should.
I'm sorry to hear about the marriage issue, perhaps couples counseling could help with that. Divorce is a terrible thing. I have been through it. If you think there is still hope for the marriage then please do something now to enliven it with hope.
Finally, there are so many other things you can do to feel alive. There have been threads on here that give tons of examples you could do other than drinking that will make you feel alive. They are in the newcomers forum but you'll have to dig deep.
Peace,
Ken
