I was literally just going to suggest Love Her Wild - was looking it up while you posted - and found I already know our local leader! Funny.
OP at that point in my life I was very lonely too. Know that it’s unlikely to be forever though. Things are constantly changing, otherwise they run the risk of stagnating!
Can you afford to work 4 days and use the 5th for something else, to be around a different pool of people to the work people. Say you take Fridays off. Start a new hobby on the Thursday night. Spend Friday getting out and about/doing another job/volunteer/indulge your passion.
EG for me and my interests that could be: Thursday night choir, Friday morning hiking group, Friday afternoon man the local craft shop. Then over time you might make a few pals from those 3 new pools of people, to then go out to the pub with on Friday night or whatever.
Communities that I’ve found to be very social are: local art scene, local music scene, choirs
Communities I’ve found to be good for surface level social interactions, to keep me ticking over for the week without never talking to another adult: library, food bank volunteering, walking around a place where people walk their dogs
You've just got to keep trying things. Through hobbies and clubs I’ve tried I’m also on 2 massive local WhatsApp groups. Sounds (and can be) annoying, but it means you can put a call out - people are always saying ‘I’m walking round the neighbourhood for an hour tonight if anyone wants to join me’, ‘can anyone recommend an X Y Z’ etc and it just opens up your network and makes you feel more part of the community ie less lonely.
Long waffle but just some well-meaning suggestions!
