Troubling Schedule

So I just turned 13 and I want to grow taller because I'm pretty short right now, but I don't know if I'll be able to with my current schedule I have going on. All days of the week I wake up at 4am in order to be able to take a shower or else my brothers will, then I stay after school for either robotics or math club and get picked up at 5. Then my dad takes me to pick up my brother, so we wait 2 hours until he gets out of marching band at 7pm. We get back home at 8 then I have to eat my dinner as quick as I can so I can practice my oboe until 10. I then pack up for school the next day for 10 minutes and it takes me 40 minutes to fall asleep, so I fall asleep around 11. I'm scared that I won't grow taller at this rate, and I'm practically begging for sleep these days. On the weekends I have early schedules for private lessons and robotics both days so I might get 7 hours at best on those days. What do I do?
