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? 
Keep on trying
Please help yourself...
I'm sorry, I shouldn't have said something but I couldn't. Bare with me while we work on it now. I hear you and I'm trying.
You are enough.
please, don't cut
It wasn't a mistake in trying to change the world for the better, although you took it to the extreme and that's what hurt you. I'm proud of you.
1. Stop putting yourself in hurtful situations to save other people's feelings. They're bad people who don't deserve you.
2. Take care of yourself, because little things will affect your body greatly.
You are capable of doing so much more than what you think; have heart -- life is tough and so are you.
Don't be afraid.
My favorite quote I've heard from one of my past teachers was this:
"Be the person your younger self would look up to."
I have two words...buckle up!!
