As an animator person with a small amount of animation studio experience, lemme say this:
There's no time limit to find work in the art world, nor is there a cut off date to start and make a project.
I didn't finish animation school until I was 22, and I got my first animation job a year later.
Even after that ended, it was another couple years before I got the next one.
You can do something that's more steady to keep yourself fed,clothed and sheltered, but still send out applications, draw your coimc and enjoy art as hobby to keep your skills fresh. Heck, I worked at a theatre right out of highschool and up until just a few years ago when an animation job started getting extra busy.
As well, as a good friend pointed out just today: J.R.R Tolkien didn't start writing Lord Of The Rings until he was 45. You're going to be okay in the longrun, so be easy on yourself and don't give up. :)
If a dingus like me can find small amounts of success and keep my head above water, so can you! Good luck!

Well, finding a stable job isn't a bad idea. You draw as a hobby... have some coworkers see your stuff... they let others know of your talent.... It all has the potential to loop back around. Most artists/animators/musicians I know don't rely on their art as a primary source of income but they still make stuff, maintain a commission page, and so on. Unless you're exceptional or really lucky, living off your art takes a long time and a lot of networking. Join contests, comment on others constantly, become part of a community... a full-time artist is a lot of work even when you're not actually making art. Hell, got a friend working on a comic, as well, and he juggles that alongside a full-time job. If that hapless degenerate can do it, I don't see why you can't.
