How can I make up for my sins today?

I'M WRITING IN CAPS BECAUSE IT'S JUST EASIER FOR ME. I SINNED SO MUCH TODAY. I LIED TO MY MOM AND MY SCHOOL NURSE SO I COULD GO HOME FROM SCHOOL. I'M A GOOD STUDENT, BUT PEOPLE WERE MAKING FUN OF ME AND I WAS FEELING INSECURE ALREADY. SO I FEIGNED A HEADACHE, AND WENT HOME. WHEN I WAS HOME, I HAD TO BATTLE TEMPTATION, & LUST. I LOST THE BATTLE. EARLIER IN THE MORNING, I WAS JEALOUS OF MY FRIEND BECAUSE OF HOW SHE LOOKED. HER OUTFIT WAS NICE, AND I LOOKED HORRIBLE. (THAT'S WHEN PEOPLE STARTED TO MAKE FUN OF ME) I WAS ALREADY FEELING INSECURE AS I SAID, SO THAT WAS HARD FOR ME. I ALREADY DON'T HAVE THE NICEST CLOTHES & NOW THAT I'VE LOST WEIGHT THEY'RE WAY TOO BIG, AND LOOK BAD. ANYWAY, THE QUESTION IS: HOW CAN I MAKE UP FOR MY SINS TODAY? I WANT TO MAKE IT UP TO GOD 'CAUSE I KNOW WHEN WE SIN IT HURTS HIM. THANKS, & PLEASE DON'T JUDGE. I KNOW WHAT I DID WAS HORRIBLE. I ALREADY FEEL BAD ENOUGH.
