Hi, first off it's fine to take a year to try and figure out what you want to do in life, especially if you have a job currently. Nothing wrong with taking a year off if you're being productive! When you do decide to start college, I'd highly recommend enrolling in your local community college. Even if you still don't have a direction, you'll be able to get your gen eds out of the way at a fraction of the cost of university. They should also have someone to talk to or email to help you find a general direction to head in.
Don't worry too much about not knowing what to do in life, many high school graduates find themselves in the same position. Just remember that you will eventually find something that you are passionate about. Unfortunately there's no trick to finding out what that thing is. You could find out tomorrow or a year from now. Your best bet is to expose yourself to as many new things as you can, you've just been thrown into the real world, so go explore it!
Also try not to hang too much on finding something that can also support yourself. Find what you love first, then take it from there.
