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? 
Don't get to uptight learn to love yourself and listen to others be happy
Forgive yourself.
It'll be ok
Love yourself first.
Be only you
You do matter.
Grow from mistakes
It gets better.
Love always exist.
Don't waste time.

Totally agree: "don't waste time". Learned that lesson by losing someone I should have cherished and now he is no longer in my life the same way.
@RomanticStorm I feel for you, unfortunately you can't go back in time: sometimes I feel like I would never want to go back anyway because I would have never learned... Other days I wish i could reverse the clock.
@ThaliaRavenclaw
Currently my overwhelming thought is to rewimd time and to kick myself into telling him the way I always felt. Its the first thing I think about in the morning and friends I've made on here make me feel so much better!
