Why not head to another meeting after work to break your old routine?
Different meetings are... different. If you go to one tonight, even if some of the faces are the same and it's in the same room , chances are it'll have a very different vibe to last night's.
Please, don't feel under any pressure to speak at meetings while you find details your feet. That isn't necessary at all. When people do a main share, they should be sharing their experiences, strength and hope. Sometimes that might sound like them talking about their current problems and how they're using the principles of the program to get through this phase of their recovery. We're not encouraged to prepare as such for doing a share. It's not a lesson or a lecture. Even if we do prepare a bit, what actually ends up coming out isn't what we prepared anyway. As long as we're honest. Maybe that's just what the guy needed to share at the time. The holidays and New Year often leave people a little rattled. Anyway. All shares are different and you've heard that one now, so won't be hearing it again eh.
