Hang in there 3Bird! You are worth taking care of yourself and your son. I am one of the very few that ended up not feeling comfortable with going to meetings (I think it was the group dynamics). I found my "sanity" when joining the gym. Got a headset and walked like the dickens on the treadmill, and lifted weights. Worked off my stress, and got a pretty decent bod in the process. My gym has free child care as well, I'm sure others do. And meetings are good, Al-anon has helped so many.
Nomatter what you do, meetings, gym, read, do it for you. As they say "fake it till you make it". You will make it!
Good luck to you.
