Congrats on one week!
While I get very lonely at times, I think it is probably been a blessing in this early sobriety (day 16) for me and those who love me that I do live alone right now. Or else I'd probably also be posting about still being a jackass. Don't be too hard on yourself. Just recognize your wrong behavior and work towards correcting it.
Please go to that SMART meeting and let us know what it's like. I don't have the option in my city and would really like to hear more about how the meetings actually work.
