I had the same experience with my first group, only about 4 people stayed they were mainly interested in how much vodka they can drink if they save their syns up, absolutely no interest for me, always left feeling down and not motivated.
had to go to a different group one week and what a difference, the leader was great, the group was great, yeah she still does the going round the room thing, but gives loads of info and the advice and tips from the rest of the gorup are fab as well.
last week after getting on the scales I had put on a half a pound again, almost didn't stay to group but had a word with myself and stayed and I'm glad I did, came away feeling really motivated and ready to start again.
My advice is shop around for a new group which can support you how you need to be supported.
Good luck
