Have you got a hobby that involves groups of people? Like hiking? Do you have at something called MeetUps in the USA? Or BorrowMyDoggy? They're safe, neutral ways to meet people. Or is there a cause you're interested in that you could volunteer for, like a homeless shelter? Or a skill you'd like to learn in evening class, like baking, where you could share an interest? Or amateur dramatics? Not everything costs money. I'm like you, but then I discovered that doing an activity is the best way to make friends because you have something in common and it gets you active too. Good luck, and make sure you enjoy the journey of finding the things you like to try, don't stress about it, have fun trying stuff.
