If you could write a note to your younger self, what would you say in only three words?
I had two thoughts. 1) Words can hurt. 2) Try your best.
What would your note say? 
Let it go.
I am glad you were reading a lot! It helped out a lot in life :) 
Enjoy every moment
I would say "listen to mom". Moms know best.
Stay in school.
People suck, expect less from people.
Apologize sincerely only
@Kashie not freak, different.
It's okay to fail but don't give up
In 3 words id say: Punch bully HARD.
If i had more id say: Youre stronger than you think, so i advice you to really punch one of youre bullies direcktly in the face. Just nock him to the grownd. Because at you age it isent elegal.
To you people reading this: you might think this is a bit harsh, but i would say it because i had to go to an aktuall terapist in my teenage years because i git some big anger managnent ishues because i had bottled up so mutch anger. Hope you understand
