Please help me finish my last year of college

I am a fourth year Economics major at the University of California, Riverside. I am here asking for your help because my father has recently lost his battle to cancer on April 9, 2019. He was the sole provider for our family and since his passing our financial obligations have grown tremendously, leaving my family and I struggling to make ends meet. My dad owned a small plumbing business; however, the business is no longer being operated due to his passing. My financial aid is requiring documentation that me nor my mother cannot provide due to inaccessibility. I am now struggling to pay alone and out of pocket $5,297 of tuition and fees. If I do not pay by September 19, 2019 at 4:00 p.m. then I will be dropped from my classes and I will miss my fourth year of my college education. My education is really important to me and I do not want to let my family down when they need encouragement most. Any help is appreciated, if not by donations, then by sharing this with others will greatly benefit me as well. 
Thank you for your support!
