Will I be able to sue my previous employer for unpaid wages?

Upon termination earlier this week, I was told that I was to come into the office today, which is pay day to obtain my check for the time that I have worked. Now that today is friday I am being told that a check has not been made for me and that I will only be getting paid for 14 hours of work when ever they do decide to send me a check in the mail, which would still be incorrect because I have worked for 34 hours. I expressed my urgent need for the funds due to tuition that I have to finish paying off as well as student loan payments, the reply to me was that they couldnt do anything about that for me and that I shouldnt have taken an authorized sick leave which resulted in my termination.
