how to deal with constant fear of becoming unemployed after studying IR at university?

i am starting university this September and i am going to study IR most probably in the UK and a a small chance in the Netherlands. in my country, ir is not a respectable degree at all, it is considered to be a subject which people who are not smart enough to do stem choose to do. i want to prove this stereotype wrong, and actually use my degree after graduation and not work a job that i could have ended up at without my IR diploma. is this too much to ask?

what would you recommend i pursue while university along with my bachelors, and in which areas a indulge myself into for greater future opportunities. i am fluent in english and my mother language but i know this is not merely enough so i consider improving my b1 level french alongside. any and i mean any advice is appreciated
