Is there any way possible that a college student can still receive child support?

I'm a 19 year old college student. I live with my mom and grandma. My mom and I have jobs and my grandma is disabled. We have bills galore and I'm struggling to make my way through college. I'm doing as much as I can as far as scholarships and financial aid. Things were a lot easier when I had extra income from child support from my father. Is there any way that I could start receiving the child support again until I am done with college?
