Really glad you have some quieter time with just you and the LF from now, @CheerBear, especially with the change in meds. Wise move not rushing any decision just now, giving the thoughts and feelings more space and time.
This friend with the book launch is someone I met on the net as a creative collaborator first of all. I've worked with im on three videos so far, mostly through net exchanges. We've been getting together in person on occasions for about a year now. He's becoming a good friend too, though I think he has millions of them! He is an interesting person culturally, rather sophisticated in some ways, which means I am still kind of intimidated by him in some ways! In other ways, he's fairly hippy. Kind of a nice mix.
There may be quite a few people at the launch. It's the kind of event that I like going too, but also find a bit intimidating on the cultural level. And yes, just the basic social aspects of it are daunting to me too.
Hoping the night at the place with the lovely garden has helped settle your loved ones for now.
