@Ari-Sorokin I hit a period like this while in the middle of my animation degree. I struggled to get up to go to school everyday and was very confused that I no longer could muster any enthusiasm for what was supposed to be my passion.
Looking back, I was depressed and burnt out trying to keep up with the extremely difficult animation program and the stress got to me. I ended up failing a year, had to do it again and finished my diploma crawling to the finish line. After I graduated was the beginning of the rest of my life. I rested, re-centered. I found a job in a studio where there was no overtime. I worked 9-5 and rested fully during nights and weekends. To this day (8 years later) I still get on the high of "I don't have homework tonight" LOL
I saw my passion and enthusiasm swoosh back to life. After a year, I started a webcomic in my free time. After 3 years I left this studio and became a freelance picture book illustrator. Since last year I switched to surface illustration. I've been following my creativity and passion where it leads me, and it has been both fulfilling and lucrative. This year I've hit 6 figures for the first time which is exciting! I bought my first house this summer as well.
Anyway. It's good that you're asking yourself these questions now. But you also seem a bit anxious and down to me which is likely exacerbating all those doubts and fears. Try to rest. Relax a bit. Draw something for fun. Take a deep breath.
At your age I was certain I'd end up an animator, but in the end I changed my mind. Some things you can only know if they're right after trying them out for yourself. Make plans to make your goals happen, but stay open to life's possibilities. A diploma is meant to open doors, not limit you.
The great thing is that an animation diploma touches on so many things that will be helpful to you in almost any art career. People I've studied with have many careers now, from animator to background artist, storyboard artist, film director, picture book illustrator, author, fine artist and more. One guy creates engravings for tombstones!
