Dollar General is bad for selling low quality products and exploiting their workers for profit. Is it so bad to want things to be less than their most shitty version?

Volunteer. You meet people, you help people, you gain confidence in yourself from helping others. Some of the best people I’ve met have been through helping others. Look at it less as trying to meet other people and more as working on yourself.

Also become a regular somewhere. Coffee shop, bookstore, etc. become known as a friendly person and you will run into other friendly people. I personally rely on bookstores and gardening to meet other people. Both are non-threatening environments that people are usually open to having conversations in.
