Bactrim and seizures

I started Bactrim for a UTI and felt horrible the whole time. Sick to my stomach, trouble breathing, headaches, loss of appetite. Once I asked my husband to call 911 because I almost passed out. But then I said, wait, let me settle down. I did that and continue with the medication thinking it was the UTI. Then I went to urgent care because I was suffering from a yeast infection from the Bactrim too. The 9th day on Bactrim I got worse, I started to break out in hives. By the 10th day I rush to urgent care covered head to toe in hives with trouble breathing and bumps on my tongue and mouth and throat. The doctor said, you're are having an allergic reaction to the Bactrim. He gave me a shot of cortisone and Prednisone l for the inflammation. My stomach is swollen, my body aches, I still have a terrible yeast infection and read that if you have fungal and are taking Prednisone, that's not good either. So I am at odds because my breathing is labored and I am hoping the Prednisone works and I can make it another day or else, I will go to the emergency tonight. This is no fun....I sent this list of complaints to the FDA's attention today. I hope they listen and look at this page seriously and all those who continue to write.
