Uhh no. Sleep is anything BUT overrated... Seriously. Try a sleep aid... Not Lunesta or anything drastic, but see if an over-the-counter drug works, and if not... Talk to your doctor.
I tried to commit suicide twice with sleeping pills a few years back. He justifiably won't give me any. I just don't sleep well when I'm sick or stressed. Both of which I am now. Its all good, though. I'll be fine. Promise.
