In this life, there are many mysteries that we discover as we grow older and wiser. You must learn that we all go through pain and misery to understand that nothing is perfect as starts cannot shine without the darkness in the night sky. We must all believe in ourselves and think of ways to make us a better person as karma will repay us with good things. I've learnt you don't know how strong you are until being strong is your only option. Be thankful for everything in you life, stop wishing and start chasing your dreams and it will come true one day.
