Here at SR and at AA meetings, it is often suggested that acceptance is one of the first steps toward change. This may seem easy to do, but for many of us who are accustomed to instant gratification, it's really tough to slow down, accept where we are at this time and put together a plan that enables us to address the very things that are disturbing us in our present situation. We also have a tendency, especially as men, to equate our self-worth with our ability to make money and provide for our families. Sometimes we find ourselves in what we consider undesirable situations, and we're unable to see the benefits or value of that situation if we're too close to it.
The problems you listed in your post have some good features that we often easily overlook. One that comes to mind is the present residence with your mother, who can be there for you, you can be there for her during this time, can build a stronger bond, and allow the relationship between her and her granddaughter to blossum and grow as well. Secondly, you may occasionally be able to have your mom watch your daughter when you need to get out, hit a meeting or just catch some fresh air. The lack of a dl is a real pain, but there are options available for transport, although some require us to ask for help, which is a real humbler for most of us.
You see what I'm getting at, this acceptance thing really does help ease the mental anquish we feel if we're able to see the options available to us as we strive to let go of the booze, dead relationships, past memories that haunt us daily and rebuild our lives anew, with a new foundation and direction.
Enjoy your weekend and next week will look much better.
