Wow, thats impressive! It is amazing what we can accomplish sometimes. For this semester I was deeply depressed, then had severe PTSD that triggered a severe mixed manic episode...or something like that. The depression is hardest on the study but by the very end of semester my PTSD and mania were making it equally difficult to concentrate and function as I was delusional and disorganised. I think I got heaps done while hypomanic and that carried me through.
