Does anyone else have this sickness?

At first I had a sore throat and had almost ped out on the train station. I woke up feeling really horrible, and my throat swelled up. The next day I went to the hospital, he just diagnosed me with a major ear infection and a throat infection and had told me I would feel better within two days. My head is congested, I have no energy, I am dizzy, my throat is still in pain and my ears are clogged. I'm afraid that I've become immune to the anti biotics because I have taken it in the past for other things. I'm going to another doctor today, but just want someones opinion.
