A more extreme measure would be going to a school that interests you, accessing their 'Academics' tab and checking their programs, one by one, seeing what each program studies, future job prospects for each program, see what sparks your interest. This one is way more time consuming but I think it is a good way for you to see the option available for you out there (which are MANY!).
Natalia recommends the following next steps:
The second thought is that the Bureau of Labor and Statistics has some great resources to help you figure this out. Projected growth fields, career quizzes, outlook for certain positions, salary ranges.... https://www.bls.gov/k12/students/careers/how-can-bls-help-me-explore-careers.htm. It can lead you to something you might want to set your sights on and possibly rule out others.
The third is to look around at adults in your life - parents, older siblings, other relatives, neighbors, etc. If they have a job that seems interesting, ask them if they would be willing to have you shadow for a day or two. My son did this and the folks he asked were flattered that he wanted to join them for a day. Best of luck!
It really just takes research! Look into different programs and see what makes you the most excited, and what can be sustainable.
You could also go to community College for a year! There may be a stigma around community College, but there really shouldn't be because theyre a great choice! It allows you to go a cheaper school and try of majors before commuting to an expensive one. It'll also help you get your gen eds out of the way.
Ask your family and friends on what your strengths and attributes are so you can narrow down the options. The cost of your degree should also play an important factor in your decisions. There are online career personality tests that guide you into what you would be good at. The reputation of the school that you want to go is also something that you could look at. And lastly you should consider that graduation rate of the college of choice.
