I've been going by to the same support group near me for years and it's so somfortable. I could not go for 6 months but when I go back I know everyone and it's easy and not awkward or anything.
But recently I've also been going to a group near where my pdoc office is, Close to where I used to live but like 35+ min away. I've needed some extra support. And it's uncomfortable and awkward as shiit. At least until meeting officially starts no one really talked to each other and it didn't feel welcoming one bit. But I have been going like a for a month now most weeks and I have starTed to meet ppl and feel a little more accepted. The ppl aren't rude or anything. It's just that wanting to say something but never seeming to ono how/when to jump in. When it feels like others are able to naturally join the conversation I sort of feel like my timing is always off and somebody else speaks just as I was about to. But now I feel a bit less awkward I am bolder to just jump in and interrupt and give my 2 cents so to speak and it has been helpful I think.
So I hope u give it a chance. The ppl make a huge difference and every group has a bit of a different personality and way of doing stufff. But overall I find it a supportive place where I can say stuff I can't talk about elsewhere.
Anyway take care.
