What stresses you out?
I know that teens have a lot more on their plates then most adults think they do. You are worried about your grades, your cash flow, your friends, not making your parents too mad, your love life, and many more things. The Health Center states that stress that is not dealt with in teens can lead to a life time of being overstressed. Some immediate effects of stress are being sleepy, ill and unable to cope.
You are the only one that knows when your stress is too much. Half the battle is recognizing that so you can take steps to relieve your stress. Health Center recommends:
-getting regular sleep
-eating a healthy diet
-taking breaks when you need to
If none of these help then you may need to see your doctor to receive more help for your stress.
