Glad you're finding it comforting, theemmadilemma. Regarding the six weeks off I guess it depends where you work. A lot of large companies used to see taking time off for rehab as no big deal, though this may have changed as austerity bites. But if you work for a small organisation it may be tricky.
Tbh, I've no idea. Could you ask human resources in confidence?
I found rehab immensely helpful. It sort of concertinaed many months of meetings into six weeks. I had nothing to do with my time than focus on my recovery. I was in big house in the country with no distractions. It wasn't posh but the setting was beautiful.
However lots of people get sober just through meetings. You need to plan to go to lots though. One meeting a week isn't enough.
I hope you enjoy the meeting. Don't feel you need to say anything. Just listening is good while you take it all in. Stay for coffee afterwards. Tell people you're a newcomer and people will offer you their numbers.
You need to understand that ringing another AA member doesn't hassle them. Helping other alcoholics is part of how we stay sober. People will want to help you.
I say people, but we tend to stick to our own sex for socializing outside meetings, unless you're LGB. Newly sober people are immensely vulnerable and should be supported by people who have no potential sexual interest in them.
