There's a screen on this page, it cant replace a formal evaluation but it might point you in the right direction. http://www.med.nyu.edu/psych/screens/depres.html
Honestly, if you think you're depressed then odds are there's probably something wrong... We cant diagnose you online, it is really something you need to go in and talk to someone about. I suggest you talk to a school counselor or nurse if possible, or talk to your primary physician. They may be able to rule out any medical reasons, and refer you to a specialist.

if you also feel tired all the time and have aches and pain it might be clinical depression which you can take pills for

A doctor is the person you ask help from in this kinda things
