I apolgise for having to admit this but I seemed to be standing at the edge of an abyss this morning, looking into a great big black hole of nothingness. Driving to work this morning, birds singing, sun shining and tears running down my face for no reason at all. Funny feeling in pit of stomach, driving on automatic pilot, unable to think properly and make decisions. Highly self critical to the point of obsession. No idea what has triggered this at all and do not really want to analyse it in case it won't go away. It's not sympathy that I need, I just need to know that this is bound to happen from time to time and that it has happened to other carers.
