Dear N-I-Z-A, it seems like you have forgotten that all those failures are just a simple test from Allah the Almighty. Remember that He will never test someone if He knows he or she cannot bear with the challenges given.
Do you know the reason Allah gave you that test? He knows that you are going to ponder about your weaknesses and try to change all that. Allah knows that one day you are going to sit for another MUET exam and surprise all of us here with your flying colors.
Insyaallah N-I-Z-A, you can do it. A small girl with a big heart like you can always make wonders to the people around you. Have trust in yourself my dear. If you think that you need someone to talk to, maybe something from a guy's opinion, feel free to come and see me. My phone line is always available for you to call or text. I have a pair of observing eyes and a pair of listening ears my dear.
