It's a really tough decision that I myself struggled with. Ended up making the wrong choices and dropped out after a year.
It was only when I was 19 I actually had an idea what I wanted to do in life, and I'm now at uni studying it happier than ever.
So I don't know what to advise you
it may take a couple of years before you have any idea what you want to do for a career, and find yourself back at college.
Just don't feel pressured that you have to do everything within a set time, like college at 16, uni at 18, work at 21. Go at your own pace if you're not 100% confident with the direction you're going.
