sleepless... vitamin D?

my friend just told me that 'having a good sleep and good a food means having a good life.'

since I haven't slept much for a week...
especially last two days... only managed to sleep about two hours each.
what's interesting here is the fact that i'm still not sleepy at all.
am fully awake!

haven't eaten much either nearly for a week.
why? cos....am not really bothered.
does it mean that i'm not having a good life?
hmmmm... probably....

I'm completely exhausted and my body is started failing to function properly.
but somehow i've managed to get some work done.
not sure how though...

shall i credit vitamin D for this?
for last few days, I've been taking vitamin D which i think helped me a bit?
