Pf you're not that old, you're around the same age as my dad and they've moved 100s of miles and have had to start again making a social life. He suffers from depression, anxiety, OCD, and social phobia so it wasn't easy, especially as he moved a few months before my mum, who he'd always relied on to be the social one. I don't want to be harsh, but I think you're lonely because you're scared of making the effort, not because you can't have a social life out of London
