Did I make a superbug?

My biotech class scared the shit out of me with antibiotic resistance. I posted a while ago about this infection in my gums, and since I cannot go to a dentist I had to resort to taking some antibiotics someone gave me. I know its not smart, but it was either that or let it get worse.

It came back. Im so fucking scared. I can't do anything about this until January. I'm scared to death. Did I make a superbug?
