Replace all negative thoughts with positive ones.
Throw away the friends who aren't worth the time and effort.
Learn to let go because it is a 'have to' and it's never an option.
Appreciate what's there for you and never get into trouble.
Be thankful for what you have.

You've went through the good and the bad. You have told yourself that you are to stay as positive as possible starting from now. You have to. People who judge you are not really your friend. Those who accept you for who you are, those who encourage you more than bring you down are the friends.

You should learn to love yourself. Never give up even when you tell yourself that you want to. You should learn how to love everything about yourself and accept yourself for who you really are. Learn till the finish line. Work hard. Promise yourself that you will.

This is your promise to yourself, Qazimah.
And you'd have to stick to it.
