Help our family keep our home while my mom beats cancer

Hi, so the woman in the picture, that's my ma. She's the entire world for me and my sister. She works as a florist in So-Cal and has worked almost every weekday for the past 16 years of my life to give my family a shot at a great life. As tired as she has been some days, she still puts on a smile and takes care of us and takes us out to fun places. She really means so much to us, but sadly, about 2 months ago, we found out she had stage 4 liver cancer. Over this summer she’s begun chemo, and she's been getting better, but school has started, and while before I worked enough hours to possibly help her with rent and other bills, now with school, I can only get enough to cover 3/5 of our rent. We ask anyone at all if you can sympathize with me and spare a bit of money to help us, about 6 months of rent is the current goal and would be a massive help whilst my mom is beating her liver cancer
