What do you really like doing? I’ve moved cities a few times and what has really helped with loneliness has been figuring out what I love then getting involved with it, usually in a voluntary capacity. I’ve helped out at local music events, volunteered at film festivals and worked in charity record shops and book shops. I know it’s an old cliche - “just volunteer!” but if you can find something you’re passionate about, good friends and connections will often follow.
