The thing is, this is sort of a last resort meant to buy me time to think things through. I feel like my life is too "planned" at times.
Well, if you trade college life for a 40 hour a week job (minimum wage or even higher) you will have LESS time to think/pray about the issue, not more. You'll never have more free time/energy than in your college days. Further, if you think that college life feels "planned" wait till you work 40 hours a week and your only free time is a few hours a day and then weekends.

A lot of this depends on how you're paying for college. I can't advise you to continue college if you're getting into major debt. I would say go to a vocational/trade school rather than load up on student loans, which you can never get away from. However, if you have some sort of scholarship or your parents are helping you with tuition, then college might be advisable.

Here's some advice from a fellow melancholic. You can't "figure out" your life, no matter how much time you think about it. You're probably prone to "analysis paralysis" and this never works. You need to just worry about the next 6 months to a year. You're too young to try to figure out your vocation now (unless you are absolutely sure and you have a clear option). But you have no options at the moment. Quitting college isn't an option that has any good outcomes.

Since the semester is still going on, apply yourself to your studies 1,000%. Give it all you got. Take your free time and say some extra rosaries. Spend time having fun and exploring hobbies that interest you. Hang out with decent friends (there's still plenty of decent people out there...most of them are "nerds" but that's a good thing. It means they aren't "popular" and aren't obsessed with superficial wastes of time). Many times God speaks to us when we're busy doing things. Over analyzing never solves anything. Make the best decision based on the info you have on hand, be bold, and go forward! God will not let you go off the path He has for you, when you have a pure intention. Many times we find what we're looking for when we trust in Him and just go with our gut.
