It is wonderful that you guys have freed yourselves at such a young age. You said that you signed up for some classes, but they didn't work out. Is there a community college in your area. They often have a class that's just one or two Saturdays in things like flower arranging or cake decorating or tole painting. It's a good way to explore things that you might become interested in.
In some neighborhoods, stay-at-home moms get together for play dates and have tea and chat while the kids are playing. Look into that in your area, too. You could organize a block party by going to your neighbors, and asking each neighbor to donate one food item and one suggestion for an activity. I'm sure you could find some ideas for block parties online, too.
Personally, I'm not terribly social anyway. Being a JW was exhausting for me because I'd rather have been at home reading a good book. I understand that each of us has our own needs and priorities. A book club might also be a good place to meet people. If you'ver never been a part of one, each person in the group reads the same book, a little bit each week, then they meet to discuss what they've read that week.
If you bowl, join a bowling league.
Best wishes with your fade. You have many years of happiness and freedom ahead of you.
