I sleep about 3 hours for every 38 hours of being up

I have been running on 3 hours of sleep for every 38 hours of being awake for the last 4 months. I am healthy and I do not have any problems staying awake, and none getting up after 3 hours of sleep.

AM I normal?

Is that normal?

I can't really not do it do to work, family, work, cleaning, personal care and then work again.

I work to much
