Can lesser amount of sleep results into mental illness?

These days a new kind of worry has surrounded me. Sometimes i get the feeling of mental illness and before that let me say that of late i have been deprived of sleep. There are some other reasons as well for such feeling. I have also been addicted to cigarette smoking. The reason behind such feeling is the kind of behavior i am showing now a days. I want to know that can lesser amount of sleep too result into mental illness?
