/// There are very few people I found who are able to be empathic in this situation.///
As this thread shows, there are some who are.
I too live alone and don't have a "bubble", so have a very good idea what it's like. Fortunately I have a few friends who get together via Zoom on a regular basis which is better than nothing. But you can't beat face-to-face as you say.
I hope the responses here have shone at least a little light into the darkness of your isolation, and that your friends soon re-establish a more suitable relationship with you. And carry on using Answerbank as one outlet for socialisation, there are some wonderful folk here (as I'm sure you already realise).
