Hello, I'm Danielle. I'm only 14, but I've had headaches, pains, and I've just been plain out sad for-god knows how long. I'm tired, I don't seem to have any energy. At first I just thought i was dehydrated- seeing as headaches & weakness are symptoms of that. but i did some reading, and i realized that i'm not dehydrated, I'm depressed. At least, i think i am. Can you please tell me?
