I understand where you're coming from. I spend a lot of time denying the severity or pervasiveness of my depression. And I long subscribed to the belief that I would feel better the next day.
It's okay to feel sad about being depressed. It is a painful, frustrating and sometimes humiliating condition. If you don't take steps to take care of yourself, you won't feel better, though. Please, surround yourself with supportive, caring people and do what you need to get well
