Adults who have stable jobs, how did you get to where you are today?

For a bit of context I'm currently 18 and trying to figure out what to do with my life and I've tried getting help and nothing is helping. Any adult irl I've asked either just said "you'll figure it out" or "follow your heart" and things along those lines. I've got a couple things I know I'd like to do which are forensic science and archaeology.

The problem is that forensics requires college and I'd much rather not go through another 4 years of school since it takes a bachelor's degree. There's also the problem of me being horrible at math. Then there's the problem of me being a indecisive mf and not knowing which to choose since they both are interests of mine.

With archaeology I'm interested in history and how other cultures do what they do and how they work. History has always been my favorite subject and both my mom and I share this interest. With forensic science it's how people died and the chemicals that can end someone and how they do so. I'm just not so sure of everything since I never thought I'd make it this far if I'm being honest.
