I think you're right that college isn't for everybody especially if you don't know what you want to do (which most people don't at 19). If you're not getting anything out of it and you don't know whether it's worth it, then taking time off or leaving completely may be the right choice. It's hard to "be successful" without a degree, but not impossible. I would suggest taking a break and using it to figure out what you want to do, then worry about what you need to do that. People care about you and they want to make life as easy as they can for you. They don't want you to make a decision now that you'll regret or that will leave you struggling through life. They may not agree with it, but it's your decision to make and you're the one who will be dealing with the consequences.

Maybe make a plan and let them know that you're going to take a set amount of time off for now while you get a job and figure out what you want to do with the rest of your life, then if you need a degree for what you want to do, you can go back and get one.
