Advice for setting healthy work boundaries?

Hey all,

Recently moved to a new state for a job so naturally the first people I spent the most of my time with were my co-workers. Then March of 2020 happened... So my co-workers became like my only friends. Now that I am able to be around people more I want to meet new people and set boundaries with my work friends to the point where they are more co-workers than friends. Any advice?
