I know exactly what you mean.
When I can I sometimes go for a bike ride and that can be pleasant, but at present it's on my to-do list (and has been for a few years) to socialise more at the weekend.
I did join a local drama club as part of my "getting out", but I didn't really enjoy the experience. The play wasn't great, and there were some nasty little politics going on. Once I move I'll look out for a couple more, but try not to get a lead role so quickly this time.
