I've found booking one or two outings a week helps with a bit of focus and breaks the groundhog day grind. It doesn't have to be anything spectacular.
Socially I've struggled because the friends that I would normally see casually are either overworked (such as my gin heavy Brown Owl) or hypercautious and not making themselves avaliable. My children didn't go to the school nursery so while I get on casually with the local school mums, I've never fallen on their radar for meet ups, and I've never quite sussed how to get in there. Normally my life is busy with other stuff and that gap isn't there, but I have really felt it this year.
Our families aren't local. DH will not be flying/ ferrying home to see his elderly mother this year for the first time. He has one sibling here, who we are actually seeing for the first time since Christmas next week. He's always very rule driven (I suspect thar there is more autism in the family than DS and that cousin...) so when the rule was 6 people at a house, that was unhelpful because 2x 4 is too many.
My family aren't local and are spread across the UK. DB and family are always overworked. Grandma-mum was ill in hopspital in Feb with her gallbladder, and I suspect came out with Covid, she certainly had a nasty "chest infection" and had a DVT scare around that time and took time to get over it. I invited myself down in June by taking flowers to my dad's grave and asking if I could pop by, but that's about the only excuse I have for "popping" when there's nearly 2 hours of driving involved. She's not feeling sociable because as well as the gallbladder being unpredictable, she has another wearing condition that had surgery cancelled at the last minute in October, then was rescheduled for March (but she wasn't well enough then). She has DB nearby. I'm actually going to see mother on holiday. She's 200 miles away and our relationship is not conventional or simple, but we're having a better phase, and with the tourism offer of 2020, I'd rather see her than shuffle around a stuffy sea life centre having panic attacks about a covered up face (the atmosphere in a Sea Life is about my limit on humidity/ sensory overwhelm anyway).
The school people seem to have a lot of local families or newly retired families with the means and inclination to come and stay, and seem to get that connection and support. We then feel like cheeky buggers asking for occasional favours because we don't naturally requite them because their families do that (which is why we get stuck sometimes, and another on the list of why I stopped working).
I'm not unsociable at all, (although I do regularly need some peace and quiet alone) I just seem to be very out of synch on practical social groups.
