I think I know what you mean when you talk about a sense of community. It is like feeling that you belong. A place where you are accepted and can open up a bit more. I so much enjoyed the feeling of belonging to a group, when I was in a weekly workshop on Mindfulness. I missed it when the 8 weeks of sessions were finished. There is good news though as another 4 week course in being offered by the same instructor and I signed up immediately.
