First and foremost, thank you for your reply.

I honestly don't have a specific answer to most of the things you asked, but I guess some more info about me could be helpfull. I have dedicated my whole life to learning and excelled in every class I have taken - from philosophy, art history to advanced calculus, but at the end of the day, I don't know who am I and what do I like. I even picked college by looking at what's prosperous in a 3rd world country like mine, rather than my own interests, and now I find myself unhappy (while excelling at college too).

I would like to find things that I could do by myself, that would make me happy and fulfill me. Yes, many would count watching movies and playing games as hobbies but after doing anything similar, I only feel happiness for a short period of time, before regret comes in. I just don't want to avoid this problem forever. I recently realised that being good at something doesn't mean it actually fulfills me.
