Denied from every single job, even Mcdonalds

I am a young college student, turning 19 soon, and have been in desperate need of money to help my family. I have applied to every single franchise in the area I could make it to, cause I don't yet have a car. I have been turned down by literally every single job and I feel like i'm lost. I applied to 3 different McDonald's and never heard back. Applied at every fast food place, never heard anything back from it. I have two years of retail experience from working at Walmart, yet I never hear anything back from retail jobs either. I got two interviews, one at CVS, and one at Alberstons, and neither called me back. I will literally do anything for any kind of job at this point. Im hoping when I get my degree and certifications I can get my foot in the door in IT, but until then I need something to keep me afloat. I live in the southern California area, which as you all may know is very populated to say the least. I don't know if there is a reason companies wouldn't want to hire me, but it really feels like it. Anyone else in the same position? I don't know what to do.
