Yes! I agree with your comments Innerzone and thank you for the support
I won't go into detail about the ideas-conversation (mainly because I'm too tired to explain it!) but I think the bottom line of all the problems these external factors have triggered, is that I should take advice, hear comments etc but as you said, work as I work best, and what come may..

About the essay...
The problem about working it out in my head and having only scattered notes on paper and in the margins of books and articles, is that now that I'm having trouble to concentrate, I struggle to put my ideas down! It's like I am very very hangover and I have to piece together the ideas lurking somewhere in my head, with the right notes that I usually remember where they are thanks to some unconscious coding of different coloured folders, notebooks etc, to construct an argument that is quite complex in itself and which the lecturer misunderstood, therefore I have to make absolutely clear...I rely too much on by brain's 'unconscious' organisational skills! And now the brain wants to shut down...
Anyway. My mum says I'm just too tired from trying to fit the entire world in my head...!!

I'll keep you posted..Thanks again for making me smile
