Your parents expect you to do it all: get straight A's, make the varsity team, play an instrument, have a part-time job. You're drowning in their expectations.
What to do: If you often feel stressed or anxious, you're taking on too much. Tell your parents you need a break. Make sure you have enough time to sleep, eat, and hang out with your friends. When the pressure's on, take stress-relief breaks. Do yoga, meditate, jog, or just chill out in your room.
