I'm a graphic designer. When I was a teenager, I enjoyed making avatars and signatures for people on forums which gave me a headstart on developing some of the skills I would use later on. My parents pushed me into nursing but after two years in, I knew it wasn't for me so I made the switch to graphic design and I'm fortunate that it worked out.
I think this path is great and I envy you a little. Very few people manage to maintain the passion of their youth and then earn money with it. I'm keeping my fingers crossed that this path continues for you!
Also got into graphic design after starting off on a path of really not knowing what to do, but leaning towards engineering. Went into that program before I just said "Fuck it, let's try graphic design instead" and really it was the best decision I ever made. Got a job right out of school, student loans paid off within 5 years after graduating and I'm in a relatively fulfilling career making more than either of my parents made.
