Welcome 
There are plenty of opportunities to socialise sober. Hobbies to share mutual interests and have a good time is a vast field to socialise.
You can search for hobbies for inspiration.
Do you have any particular interests? Bookclub, gardening, sports, history, crafting … ?
Also volunteer work is a great thing to spend time and get to know people.
I myself live a very reclusive life because I like it that way. I love to meet friends (mostly we go out eating or for a coffee), go to a classic concert or to the theater every now and then, i do volunteer work in seed saving (great people and always interesting), i like a good chat with my neighbours.
I’m not into church or any programm, so I have no experience in socialising in those settings.
Sending good vibes, you are not alone
