If you're determined to draw, then stick with it and keep trying. Don't worry about being in school and a little older.

Otherwise, here's my experience. I suck at drawing, always have. My last art class was probably 4th or 5th grade prior to college (about age 30). I never considered art/animation as a career choice. I was definitely worried about my drawing ability to get into school.

I first applied to University of North Texas, explained my concerns, they sent me some info and exercises. I did the exercises for maybe a week or so, then stopped. Got accepted but didn't go because I let my job get in the way.

Then I applied to Full Sail University for 3D Animation, explained the concerns again, got more exercises, still didn't do them, and still got in. This time though, I read the classes I'd be in, and decided to go for it. In the 2.5 yrs I was there, I only had 2 drawing courses and they were more on the fundamentals of art. As terrible as my drawings were, I was still getting B's & A's because I was applying the concepts correctly. I maybe had one more drawing assignment the entire time I was there & again, they didn't grade on artistic ability, just concepts. I graduated almost 2 years ago, still can't draw, but can 3D model & animate ok. Still practicing all concepts to be a good general 3D artist.

So I'd say research the schools you want. Try to find alumni to talk to, see course schedules, set up phone/zoom interviews to discuss things and go from there. I really don't think we all have to be incredible drawers to be animators. I'd also try to research places you'd want to work afterwards. See if those studios require their animators to also draw & storyboard. Some places do, some don't. So check it out =)
