Looking for a job in miami/doral/kendall area

Hi, currently desperate for a job right now I am homeless living in my car with no ac for about 2 months. I’m 18 in college with only 2 jobs as past experience and while i’ve been getting interviews, i havent been getting hired, i always call back or go in person do whatever everyone tells me but hasnt worked out for me yet and its very discouraging for me as i spend each day in the heat. i just paid my car insurance that has split my few savings in half after holding out as much as i could. please, if maybe i could use someone as reference or be directed to more places hiring that would be extremely extremely helpful. i am just very lost right now and panicked while trying to keep up with my classes so my grant doesnt get taken away. im embarrassed posting on here but i dont have anyone in my life to ask for any kind of help
