I didn't receive a W2 for 2018. I was full time student, no job. Some classmates said not to file since I had no income & will get $0 return. Still want to file

I was unemployed all 2018 since I was full time student. I did not  receive any payments, I earned zero dollars and  therefore,  did no  get a W2. I'm  assuming since I did not make any dollars, I will not get any money return nor owe to IRS?  I still  would like to  file  2018.
