I shall in no way prevent you from any Horary Reading if anyone is willing to do it....but your request flabbergast me a bit...and I will give my view on take it or leave it basic.
You wonder if it is your destiny to study Literature.
It flabbergast me a bit how often such question occur, because if you think about it...if destiny is something firm....that is set..then this will happen whatever you do....if so...then why will the "destiny" change with what Reader you approach..and what time you ask the question.
The Destiny is in my way of belief much up to what you yourself create it to be.
It depends much on your abilities, it depend on your interest, it depend on who you interact with, it depend on who you get as teachers, it depend on your abilities to focus and work toward a goal...and so on....
So if a Reader tells you that your destiny is to be a Doctor, and you focus on this task, and have abilities inside this field, then you will become a doctor.
If another Reader tells you that you will become famous in Literature, and you have abilities inside this field, and put your focus on this task, then you will make your destiny as a Liturgist (or whatever the word is

)
If a third Reader told you that your destiny was to become President, and you had the abilities, and "the backup" from parties that would see you as such, together with the finances, you would become President...b
So Destiny...or Future is something we create as we go, and depend much on our goals and the work to see it through.
All Readings, included Horary, can give you suggestions....BUT only you can make them come true with your own work.
Back to your question.
You have study for 3 years....you have now got a good view on what your education is about.....your question must be....is this something I want to do for the rest of my life....is this something that gives me pleasure beside the salary...or will I burn out?
If your question is negative....then end your education...you are young...you still have time....BUT...be sure that the education you then start is something you really want to do....that you have abilities for it....that there is offered job for it in those places you want to live....if you do that...then I am sure you will succeed in whatever you choose to educate yourself in.
Good luck!
