CV is right, there is not a whole lot of traffic in this forum.

Small steps?

It sounds like maybe going for a walk and deciding that you will say hi to people you pass would be a first step.

Or, calling people. I hate making phone calls, even easy ones. That might be a first step.

Another thing you might want to try is volunteering. For me, it has been easier to get out of the house if I knew that by doing so I would help someone who needed help.

And, I hope your appointment on the 18th goes well.
