just finish your exams. finish school and then figure out what you wanna do. Webtoons and animation are a lot more work than just studying for exams, just being good at drawing doesn't cut it. Figure skating is a brutal sport. If you can't even finish school, what makes you think that you can realistically keep up with the extremely demanding effort it takes to be good enough at "cool and fun" jobs to make a living? Finish one thing before starting something new because you can't run if you haven't learned how to walk. Feeling like you're running out of time or being stuck is a universal experience. Many people go through these struggles in life, especially when we're young. You're not actually running out of time because you're young and have your whole life ahead of you. Try organizing your thoughts on paper, write down short term and long term goals and how you can achieve them, maybe you will feel less lost.

Who cares if you're a disappointment to your parents! Their approval only has as much value as you choose. Living for your parents approval will never make you happy, because you won't be living for yourself but for them and frankly, that doesn't sound much like living to me. 

I do recommend therapy or counseling, it helped me when I felt lost and stuck in life. It taught me how to actually live life and not just survive.
