Help my family not be homeless pls

During the past 2 years we have had to move 2 times due to a lack of income. This upcoming September we will most likely have to move again. My mom needs a double hip replacement and doesn't have the ability to get it done with her working 2 jobs just to be able to get groceries. As a full time student I'm unable to provide as much as I want to to help her due to my paychecks from my 4 jobs going towards my loan payments. My sister works fulltime to support her own bills as well as the bill pool for our family.
Just to have enough to get us to August rent would help wonders.
