   Puberty can throw your hormones into turmoil and cause all sorts of strange things.

   Depression causes feelings of sadness (even when the circumstances do not warrant it). In some, your sleeping and eating can be too little or too much.

   Depression alters your way of looking at the world, everything is grey.

   How is your school work, social life, situation with your family?

   I love to sleep late and like being alone–been that way my whole life–but, I'm not sad.References :
