Follow-Up from the LGBT group post

It couldn't have gone worse. There were only two other people, a girl and a heavily disabled guy. We just sat around with the lady running it talking about how to get more people in and going to an event, which I'm not keen on doing.It was so humiliating and awkward, but now I'm stuck in a dilemma. Because it's such a small group and they're trying to get more people in, I'll feel like an asshole if I leave. But at the same time, I really don't want to go back.What do you think I should do?
