Struggles with find a job

I've applied to 100 jobs this month. I'm a 19 year old college student. Never worked before except for some volunteer work at a park. Every job I apply to keeps rejecting me. I've applied to McDonald's, I've applied to Amazon, I've applied to chick-fil-a, I've applied to Starbucks, I've applied to fed-ex. Literally every single low-paying job you can think of I've applied to. Why can't I find a single job? I'm so desperate and yet I can't even become useful even when I beg on my feet to do so. I really don't want to waste another summer, and yet even in a month of applying I've gotten nowhere. This is half me asking for help and half just venting, I just don't know where else to express this.
