Don't know what country you're in or what school you want to go to so depends. If you're debatingbetween doing art and a career that's deemed more stable, you should definitely listen to yourself above all else and know what has the best longevity for you mentally. Art education is really all self-taught + on the internet. but there will always be a factor that you'll miss if you just train yourself and rely on tutorials and that's people, you learn extremely fast by being surrounded by like-minded and talented people. So school would begreat for that but if you can place yourself in a situation where that's replicated or school isn't important that would be ideal.
