Suzi, not sure if this is an issue like mine.
Friday - Feel at my best as I know I have days away from work. Saturday morning generally okay, but Sat night start worrying that Sunday is coming and Sunday being close to Monday morning. Sunday I spend "depressed" that after the next sleep Monday appears. I find work hard, but not dreadful but on Sundays I really am at my worse. I have spoken to friends about it and none of them have depression, feel something similar on Sundays. I think we just feel it more.
