Not too terribly isolated.
I Skype with my daughter every few days, she's trapped in the UK right now and not at home here as planned. This is perhaps the worst isolation for me, as we had all sorts of fun plans.
I Skype with my Dad for lunch a couple times a week, seems to cheer us both up.
I see my Mom in person 3-4 times a week, from a safe distance, as she is quite vigorous about her quarantine efforts. Sometimes my sister and her partner are also down there and I can chat, from a distance.
I have a Zoom class once a week on "literature of the pandemic" with about a dozen other local folks, taught by my neighbor the recently-retired professor, that's a lot of fun, and a ton of reading.
I have a Zoom "beach party" with co-workers from Silicon Valley I haven't seen for years, it has been fun seeing old faces and making new friends.
I have coffee in my cul-de-sac with the two other households who are on the same circle - we each set up chairs/table at the end of our driveway, we are probably all 20-40 feet apart.
My "friend" comes over for 3-7 days at a time, every week or two - they live on a nearby island, isolated, and we've combined our households as a "pod" after some amount of quarantine activity, and we reset a quarantine time whenever one household has perhaps been exposed.
I have my friendly bloodhound and satanic cat here full time as well, and my new vegetable garden out on my deck also provides company. I had to put up scare-owls, as the birds were eating all my berries, otherwise I'd have plenty of birds here too.
I am avoiding most non-essential human contact except from a great distance however. I live right next to a large state park that gets hundreds of thousands of visitors a season, and even with all of our restrictions here, the place is packed, so I don't feel so motivated to be over there right now.
