Okay. This is, the main problem. Onestly : sometimes your parents can be very boring and they always tell you sentences such as:
STUDY
TAKE OFF THE PHONE
TAKE OFF THE EARPHONES
TIDY YOUR ROOM
PREPARE YOUR BACKPACK
EXC
All of this is very very stressful and at the moment you' re think: my parents suck!
But, don't forget: parents want the best for you and they advice you when you're doing the not-right-things.
So, try to talk with mum and dad about your problems, explaine you reasons and, finally, try to listen them. Your parents love you and they have been teenagers, too!
