how do i find out what to do for college?

i have no idea on how to write blogs and english is not my first language but i figured i should at least talk about it because this is my last year in school before (hopefully) going to college. 

So, the thing is, i love art, i've been drawing since i was a kid and it's something i'm really passionate about and ever since i was a kid my dream was to write/ilustrate comics and stuff like that. But i do know that i can't do that for college since, yk, i would have rent to pay and i dont think i can get money by drawing and making comics or whatever, especially in my country. Although it makes me really upset, i have been dealing with this fact for years so i guess i kinda accepted it as time passed. I can do it as a hobby, but not as main job.

So what do i do for college? How did you guys find out what you could do for college that you liked and would also give some money? i need to know so bad, because i cannot think of one thing aside from art and history/sociology that i can picture myself being happy doing it in college. I'm scared that the only realistic future of myself is the one where i'm unhappy and i dont know if itll actually be that way or its just this anxious feeling you get before getting into college. My interests are music, art, history and sociology but i cant imagine anything that i could work with that would have these things. Is there anything close to it that i could do?
