For zoom you can just log in and remain off cam. If anyone asks you can just say you are new and that’s it, you are under no obligation to talk or participate unless you want to of course. My advice is do a few and sit and listen, try not to judge (it’s hard at first) and hopefully you can identify with what you hear. It’s always good to be around people the same as you.
I don’t subscribe to just one method, I thee everything at it, AA, counselling, trauma work – all sorts. Its your life at the end of the day and it’s worth something!
