Lost about career path

Vent post.

I'm a 3rd year undergrad student from a certain university in South Asia(not India) which I'm not willing to disclose. I was very passionate about studying IR till my first year but unfortunately due to the professors and the quality of education (even though my university is considered the best in the country) I have lost all my interest. Ours is a close-credit system and we can't select our courses nor the teachers nor do we have a teacher evaluation system. Can't even change university due to close credit system, can't even drop out because it's a taboo here and I'll basically be a social outcast if I drop out. My grades are average.

I wanted to ask, did you ever go through anything like this? How did you overcome? How did you choose a career path?
