Experiences good or bad?

I have procrastinated around this and finally joined the site but had a look around it and tbh feeling a bit overwhelmed. There are so many and some of them are so specific and a few quite exclusive (niche hobbies and professionals).

I guess I just want to meet some nice people, but not specifically a hobby, and it will have to be women only because my husband gets jealous if I spend time with other men. I noticed there are a few women only groups so I am trying to pluck up courage to go - but I am nervous.

I don't exactly have full blown social anxiety but over the last few years have lost more and more social connections and feeling a loss of confidence because of this. I find the whole idea of approaching a group of strangers worrying and a bit scary.
