Why don't you join a gym? - get into a class, you're bound to make friends there. If that's costly, then maybe look for your local sports teams and join find a new hobby. If that's also costly, then try reading or teach yourself something new (maybe a new language) visit the library, make friends with the librarians! If that's not your thing, why don't you try writing to your local care home, there are many elders who are just "dumped" there - it'd do both of you good to have someone to talk to. Apply to volunteer in densely populated locations e.g. cafes, hospitals, supermarkets - it's good cause you'll get more work experience and make new friends!
