Be careful not to fall for the "we're a family here" corporate tropes and then have an existential crisis once you get fired or laid off. Work is work. Your customers are not your friends and your coworkers are not your family.
Coworkers might not be your family, but it doesn't mean you can't be friends. Some of the people I'm closest to I met at work, however to ensure our interactions aren't constrained to the workplace, we've made deliberate attempts to meet up outside of the office.
The friend I'm closest with I met at a previous job and we continued talking and seeing each other after I quit that job. Your coworkers are not your family, but they can be your friends if you let them, and that relationship doesn't have to end when the professional aspect of the relationship ends.
