Am I asking my body for too much?

To start off, I'm 15 years old, and a sophomore in HS. I'm almost 5'8" and I weight about 117 pounds. Most of that weight is muscle.
I run track & field and I'm really good. I work extremely hard every day (my hs has an extremely good track team) I sprint 200's, 400's, and I do hurdles. Despite being only a sophomore my coach is considering putting me on varsity.
So, I run track every day, and I work my ass off. Two days a week I stay after school. Monday we work on hurdles and Tuesday we work in the weight room. This is after normal track practice.
Tuesday, Wednesday, Thursday, sometimes Friday, and Saturday (and sometimes Sunday if I have a horse show) I ride horses. I don't ride as a hobby, it's my sport and I ride competitively (traveling for shows etc.). I ride for an hour or more every day but Tuesday, when I ride for half an hour. I'm at the barn for about two and a half hours, one hour riding, the other one and a half cleaning my stuff, taking care of my horse, etc. So in addition to track every school day, practices after school sometimes, I ride almost every day. That's a LOT of exercise. I'm extremely serious about riding and, again, work EXTREMELY hard. The level and type of riding I do requires physical and mental strength. Physically, it is very tiring - jumping a 3'6 course of fences and having good equitation (form) takes a lot of strength and work. I can't stress how important riding is to me, it's one of the most important things in my life and even if I can barely walk after track I still go and ride my horse.
In addition, every day but Wednesday I do core and quad workouts. Leg lifts, bicycle crunches, planks, wall sits, squats (without weights), push ups, and a LOT more. Most days I am so tired by the time I go to bed. I have an extremely small appetite (though I eat mostly healthy) and I'm worried that I'm overworking myself… I'm extremely competitive and always want to be the best, and I'm obsessed with not being fat.
