Whats the best method for finding a new job while working 7 days a week?

Im getting tired of being forced to work all my free time away… but at the same time they make me work so much i have no time for interviews… sure i could just quit and i have enough money to last at least a month… but im just gonna panic till i get a new job if i quit without anything lined up… makes me nervous not having a source of income i just cant stop thinking about what if i cant find one and i end up homeless over this
