any advice to actually start doing what I want to do in life

I just entered my teen age 3 years ago, and ever since I was so pressured to know exactly what I want to do in my life, because other people who's younger than me already knows what they want to do with their lives and I remember being jealous because they can start working on whatever it is they want to do with their lives, so by the time they get older their already good on what their doing and they can start profiting on their passion, and that's exactly what I want to do I want to profit from my passion, but growing up I didn't have any so I was so pressured to find my passion, but instead I just tried to become open minded to the things that can be my passion, and now that I find my passion. I want to become an artist, but because of my illness everything for me is harder to do than normal, so I tried to have a role model and I got kurt cobain for example I want to be artistic like him, and now that everything is figured out. I just need more advice to be more productive during my rock bottom that cause by my illness ever since it got worse because of the pandemic. But anyways any advice will be appreciated. Thank you in advance.
