I also thought a depressed person goes to bed and pulls the covers up over their head. Although i feel like that most of the time. I have 4 kids and havent missed doing anthing for them. I dont have a problem with sleep or eating, or crying. I have no hope for the future, look forward to nothing. And dont enjoy anything. I have shut off feelings and just go through the motions. I dont laugh at jokes and the negative thoughts are all thats there. You dont need to have all the symptoms, just enough of them and the severity is different for everyone.
