You're still growing if you're only 5'10 with the potential to match 6'3 or 6'4.
But seriously, consider eating more lean protein, vegetables and fruits. Also, carbs are still going to be your friend for long-term energy use. I would just consider getting them either steamed, boiled, or baked. Limit the fried stuff.
I saw in another post that you ate a package of biscuits and coffee. That's the worst breakfast for an athlete. You should eat something with more nutrition and protein to build & fuel those muscles. Coffee also is very dehydrating, so you'll need to drink more water.
I know you have access to the internet. You'll want to consider a meal guide from men's health meal plan, 1 of many, from mens healthor live strong. meal planning through Livestrong.com
You might have to take up cooking, but it's a good, life-long skill to have (also, fyi the sexiest date I've ever been on was when a guy walked me through a meal as he was cooking. It was very much an adult date, but it's a date that should work on any gender, if you needed motivation about the cooking. This feels so wrong to be telling this to a teen but it's real advice.)
Consider talking with your guardian about a nutrition coach/registered dietician. Sometimes health insurance plans will have one available, your primary care physician will also be an ok resource, but most Dr's take 1 class on nutrition and the real experts are the registered dieticians (RD degree). Anyone with a degree in sports medicine is also a good resource for a growing athlete. Your own coach sounds like an untapped resource on meal planning/nutrition guidelines. Talk and ask questions from your coach(es).
