If you had acquired a new case of oral HSV 1 infection, I would expect that you would also have some external manifestation - like sores on the lips. Have you ever in your life had a cold sore on your lip or on your nose? If yes, then you already have herpes in your oral area. If you are improving on antibiotics, then that suggests to me that your doctor was correct in the diagnosis of a bacterial infection rather than herpes in your throat.
To answer your question, I think you are being a bit paranoid, and there is no serious risk, given your improvement and the lack of other visible sores in the oral area.
