Hi..I'm pretty much the same as you, though I have been diagnosed as clinically depressed years ago. The thing is, with me at least, when I'm down, I pull away from everyone and sleep and sleep some more. I've slept at times from friday till sunday. I guess it's a way to deal with it. Maybe we all expect too much from ourselves? No one, no matter what they say, is happy all the time...and if they tell you that they are lying. !
