I feel like I've made a mistake in studying graphic design.

A little less than a year ago I enrolled in a private university in my city to study graphic design (literally my only option to study what I wanted without moving out of the city) and at first it was fun, they had us do simple things on photoshop and illustrator as well as some sketches before any big project. However ever since I enrolled I haven't felt like drawing what I want in my free time, after each project and every homework I do I just feel so drained from drawing and art in general that I want to do literally anything else in my free time even through I have a bunch of ideas for things I want to draw. Every day I always feel as if I should've picked a really easy thing to study like philosophy or whatever and do art in my free time so I can get better specifically in the areas that I want to use to make some sort of career for myself.

So I want to ask, did I make a mistake in choosing to study graphic design?
