should I quit?

Been working at this restaurant for almost 2 years. Frankly I’ve never been given my preference for amount of shifts (I would love 2-3 sometimes 4) usually get at least 2 but have only been given 1 shift for the past two weeks. I am not a seasonal employee and work for this restaurant all year while students come and go but they still get more shifts than me!!! I have had MULTIPLE conversations about this with the managers. I cannot afford one shift but don’t know if I should just stick it out. Any advice??
