i feel your pain, for the longest time i've had bad anxiety with homework in general and not just anxiety with papers. no matter how much i want to start my work or finish it, it just wont go away, so i told my pdoc and she gave me something to ease the anxiety to the point where i could actually sit down and do my work. and i also agree with the previous reply, just sit down and wright what you can. before my pdoc gave me the med for anxiety and i had to write a paper, i would write a few sentences, then stop, walk around a bit, and try and write some more. i also tried doing things that would relax me, such as reading something fun on the internet.
