I've had the same problems, horizon. I used to be a part of a lot of groups/organizations, but they were relationships that didn't extend much outside of those meetings. It can be hard getting out and being social if you haven't been for a while. It's like riding a bike though. Once you jump in and really commit, your skills will come back to you! I'm sure you haven't lost them as much as you think. We are our own worst critics.
