And then you tell us, on another post, not to worry about your depressive moods! Of course we worry about you, nailit, we probably understand you better than the people you meet in 'real life'. We all appreciate you and your good qualities.
We are also real, believe me, just you can't see and touch us. 'Existentialism' sort of expresses your current idea, but that is a philosophy - you have a problem. We want to help you, but you must act on advice.
Lack of food can lead to mental dissociation with reality. sp(numbers) came up with a good idea in saying drink water with sugar in it to get a start. There is (or was) something called 'Dioralyte' which you can buy at the chemists, it's a sachet of crystals to dissolve in water and it supplies all essential minerals - it's used for convalescents.
You've posted whilst I am writing, I'll read it and see if that helps me to say anything useful. :) x
