I get what you are saying...
I'm a bit similar, I often wonder if I am being lazy, but when you are depressed its not being lazy its all you can do... I don't know how anyone can say someone else's MI is "mild".
Also we all have different personalities, some people are structured and consistent and others are more flexible but less consistent - that doesn't make one better than the other, just different.
I've learnt to live with who I am and just do the best I can to structure my sleep, eating and exercise - I often fail but keep on trying.
