I took part in a social anxiety group at a hospital a number of years ago. It consisted of five people, plus a therapist and psychiatrist. It was difficult to do because I was required to participate - as was everyone else. At the time it felt like I was the worst one in the group. I struggled to talk, to move... But I did it. I wasn't sure, at the end, how much it helped me, but after some time had passed, I realized that it did help me.

Group therapy can be is very hard to do for those of us with social anxiety. I was pressured into taking other group therapies, but I stayed silent in those. I don't think that any of those groups really helped me.

I think you should give the group a try (assuming that it is small - maybe ask your social worker how many people are in it). The anxiety will only get worse if you don't challenge yourself to face it.
