Yes, I was somewhat of an introvert before the pandemic, and find myself to be the same introvert in the midst of (and soon recovery from) it. But, I guess it is the SENSE of lack of ability to do things that gets to me. If I wanted to hop on a plane to go wherever tomorrow, it would've been possible if not for COVID - so hopefully vaccinations continue to roll out, and this thing is over sooner rather than later. So I see where you are coming from, and Midnight.pub, and Write.as, and occasional e-mails sent to/from people I keep up with on RSS feeds has kept me sane/stimulated.
All the best
