Teen emotion overload!

We all know that being a teenager can be full of difficult, sometimes stressful emotional experiences. A new study sheds light on a possible reason why. National Science Foundation-funded researchers discovered that adolescents don't distinguish between negative emotions as clearly as younger children and adults. The Harvard University team tracked how 143 participants, ranging from ages 5 to 25, reacted to negative images using words like angry, disgusted, sad, scared and upset.
