How can I get stronger, naturally?

Question

Okay, I dont know if im in the right section, but here's my question.

Im 14 and im into working out. I weigh 159 and I have been working out for about a year now.

My bench max (maximum) is 210. But it was the same thing 4 weeks ago!

Now a year ago when I first started to work out, I only benched 105. It has doubled since then. But every time I maxed out
(benching as much as you can 1 time) I usually go up 10, 15, and sometimes 25 pounds!!!!!!

But today I was trying to bench 220, and I got it halfway up, but then my arms started to give out and my spotter came in and took off the weight.

But what happened. Why didnt I go up?

What can I do naturally to get stronger?

I have a healthy diet, and I exercise regularly!

*I refuse to take steroids or supplements, they get addicting with bad side effects.

Im only a Freshmen in high school and everyone tried to console me, but I dont feel I let them down, I let myself down.
And that has made me unusually irritable.
