Hi Dee, welcome! I am also in the UK and a former binge drinker… And can totally relate to that cringeing feeling of all the stuff I really wish I hadn’t done. And that’s just what I can remember!
Something I noticed after stopping drinking, is actually how much other people really drink. Sure I had a few friends that drank as much as me (some more), but the majority didn’t.
As I have become more solid in my sobriety and found my sober groove, I have naturally gravitated more towards the other non-drinkers when I meet new people/ at work/ through hobbies. It gets easier, with time and patience!
This community was my recovery network l for my first couple of years of sobriety and it worked for me, although I have recently started dipping in to Recovery Dharma meetings for a local network… Hopefully not too long before we can get together in person.
There are so many options, it’s just finding the right thing for you 
Would recommend this thread as a good place to start for lots of links and useful info about the forum and sobriety in general -
And I have added a ‘binge drinking’ tag to your post, if you click it you will find other topics with information that might be interesting and helpful to you
