[I had started going to a local pub, got to know a few regulars there, but then realised that they are not the sort of people I want to be friends with. There isn't much else to do locally.
I travelled into the city but I had to leave as there were happy memories everywhere of W and I, and there were families having fun. I had to go home as I was too upset.
I am confident enough to talk to strangers to start a conversation but I don't know anyone locally to go for a day out together etc.
I dont know much about UK, but in the US, there are tons of meetup groups or other boards on facebook/social media for people of like minded interests to get together to do things. Hiking, board games, book club, knitting club....whatever your fancy, Ill best there is a group out there. Making new friends and trying new activities is an INCREDIBLE way to build confidence and keep your mind occupied.
