sleepless

two sleepless nights can turn you into a wreck, believe me. this happened to me on wednesday and thurday… i simply could not sleep. each time i was about to fall asleep my heart started racing like mad and i became more awake than i wanted to be. i virtually rotated in bed, sweating like i just rode 35 km on my bike in the blazing sun. it was simply frightening and i could do nothing about it. just waiting until morning comes and trying not to panic! and the worst part of that insomnia is that i cannot explain why it happened. am i about to break? is the whole PhD thesis stuff getting too much?
