How to find something that actually makes me happy?

Title. Im tired of feeling empty all the time.

A little background : - Im currently studying engineering (freshman) although i did actually want to major in physics (I like learning how the fundamentals of the universe work). I slacked around after my parents said i couldnt major in physics (due to financial condition, the pay off in my country isnt that great for physics) and got in a very low ranked college due to my habit of procrastination.

I finally decided to lock in after getting into college but i realised very soon that people here have a very low caliber or aren't dedicated to what they are doing at all. Due to the college being very low ranked, the teaching quality is very low and difficulty of the course is in the dirt (since they need a very high rate of students passing). I score high very easily without effort and don't feel any excitement in my coursework anymore.

I've only ever been good at academics and never had any real hobbies, I dont even have any friends due to my social anxiety (i cant even maintain eye contact). I want to develop some type of hobby that will keep my mind off my emptiness, let me apply my head and let me learn something new constantly.

TLDR : Only good at academics and no hobbies, want some subject to learn or some hobby that utilizes logic instead of memorization to keep my mind occupied.
