Many adults see teens as energetic．Many of us see ourselves as proud．This thinking 1 many adults and us to have the idea that if we can't handle school or 2 life well, we are just not trying hard．
But in my opinion that may not be 3 ．
Earlier this school year, I was leaving my class one Friday 4 suddenly it 5 like I had pulled a muscle in my back．I knew I was ill．
After a few days I stopped eating．This meant I lost 6 ; the clothes that I bought two weeks earlier began 7 loose．This time my parents got scared．
8 , I started sleeping less．My eyelids(眼皮)were constantly 9 ．
I refused to 10 that I was ill．I kept my job working 25 hours a week in a shop; I didn't 11 any classes．When I was hurting, I didn't mind and kept on going． 12 it kills you, it makes you stronger, right?
But now I find myself thinking．Is it 13 it? I'm taking the classes and working for the newspaper because it does good 14 college applications．And I'm working 25 hours a week so that, once I get into my dream school, I can 15 it．
Here I am, already sick from the 16 of work I'm doing in and out of school．So, what good is a(n) 17 application if I'm badly ill? What is the 18 of doing this work if I can't enjoy the results?
In fact, by writing my 19 I'm telling all the people who 20 much about the future to worry about it now．
