Dear Madam The informational provided is insufficient to infer as depression. It is also not clear what do you mean by moody. If 10 hour sleep is not you typical sleep hour then try to adjust the hour of sleep as changing sleep pattern often results into such symptoms. If you are suffering of persisting pervasive sadness or irritability with loss of interest or pleasure accompanied with weight loss or weight gain, insomnia or more sleep, slowness in activity,fatigue or loss of energy, feelings of worthlessness or guilt, diminished concentrate, ideation of self harm then most likely it is depression. If you feel that these symptoms is applicable in your case then antidepressant may be helpful. Dysthymia is other condition in which depressive symptoms appears in mild severity not affecting much of your activity but mildly disturbing. Some tips that may be helpful are- Cultivate supportive relationships(Turn to trusted friends and family members,Try to keep up with social activities even if you don’t feel like it), Challenge negative thinking (Think outside yourself,Allow yourself to be less than perfect,Socialize with positive people,Keep a “negative thought log ), Take care of yourself (Aim for 8 hours of sleep,Expose yourself to a little sunlight every day,Keep stress in check,Practice relaxation techniques),Get regular exercise, Eat a healthy, mood-boosting diet.
