Good luck joining group - my group is really sensitive, they don't even say out loud the loss on the scales, or weight I am. they're not allowed too, then the consultant when she goes through everyone will announce loss, and we clap to celebrate and support, if it's a gain she mentions the total lost to date so still get a clap and support, but will check you're ok moving onto a loss again and if you need any help etc it's talked about then.
Really hope you get to group and enjoy the experience. You could ask around your friends too, see if any go to group as you'd have company, save £5 and they'd save £5 too.
you never know if you think about it, you might realise you have a friend who goes.
Let us know how you get on.
