If you have the chance, write a letter to your past self. What do you want to say?
Don't commit suicide by jumping off the building? Don't agree to your parents' divorce? Don't want to graduate early?
Study hard, work hard, and love yourself well.
Even if no one loves you, you must know that I love you very much.
Don't cry, don't be sad. Don't swallow your tears alone when you are sad.
Keep smiling, love the sunshine, and seize every day of your life.
