Hi guys. Quick question. It took me a long while to realise the links between lack of sleep and depression. Now I try to get as much sleep as possible. Today I am very tired. In fact as the day has gone on I am beginning to feel quite low. Not depressed, but certainly tired and irritable. Why is this? Do 'normal' people feel depressed when they are tired? Does this mean the depression is there waiting to jump out and scare me if I have two late nights in a row? Answers on a postcard please. naswm x
