Ever dreamed becoming an artist/writer? did pursue it or not? why???

Do you guys ever wanted to just make your own story and draw because your head is full of ideas and imaginations but you can't because you aren't really an "artist" who can draw and a "writer" who knows what exactly to write?...
I'm in the middle of my first year as a college and I have chosen a path that is clearly far from becoming an artist and writer.
I keep having those nights where I over think about novels, webtoons , manga, stories that I've read and I keep having ideas like "oh it would be better this way" "they should've added a character like this like that bla bla bla" and then suddenly I would come up with creating my own story... something like that.... and they are surprisingly good....(i mean the story i created) well at least I think I can satisfy people with it...
So yeah it was always like that and i feel like in the future I really wanted to become someone who writes and and draw. I really makes me happy whenever I come up with ideas and really good imaginations. Writing is not a problem for me but drawing....errrr... it's not that I'm very bad at it.... but the thing is I don't really have time to practice since college is eating me alive and I chose a random course (really far from journalism or media/fine arts) I should've got those course but now I'm in agony.
honestly in my country people would think that I'm such a nerd or otaku something and being an artist is hopeless. (though I'm not exactly denying that I'm a nerd, otaku and hopeless artist) .... maybe another reason why i didn't choose that path is because I wanted to live "normal" and go with the flow with common people....
I'm still in my first year... should i shift my course and chase my dreams?....
so how about you guys? can you relate?
