You could also look up symptoms online of Major Depressive Disorder, Bipolar Disorder, Dysthimia, Cyclothima, or any of the other mood disorders (though those are the big ones for kids and teens). With a bit of looking, I'm sure you could find a site to post a question for a doc. or a chatroom, something like that. The APA might have something like that. Also, look for local clinics that offer free depression screenings - it's not at all uncommon, though I don't know where you're at. Another stop would be the library. There are loads of books on teenage mood disorders. My recommendation would be "More Than Moody" which is geared towards parents, but covers all the mood disorders from an adolesent stand point (remember, almost all depressed kids and teens exhibit symptoms of ATYPICAL depression, so don't find info for adults and assume that you're not) while remaining fairly readable. Good luck.
