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? 
You are perfect.
Shut your mouth.
Your size doesn't matter.
neither do your looks.
And for the love of God put down the razor flush the pills. It gets so much better.
Don't try to change who you are for anyone but yourself. Only if you truly want to change, not just because someone else wants you to.
She's saying more
I have two thoughts: Find the light Don't get depressed.
You don't have to explain thing to the others, your life is your life and what you doing with it is your choice.
Never miss a moment with anyone because your going to lose a lot of people while your young. Stay single, everyone will hurt you. Even if it's in your head that "she is different" don't do it! Get a career so you can take care of mom and dad. There health gets a lot worse also while your still young and neither have money to survive or you for that matter! Get your $h!+ together.
Change course now
