bacterial infection
"I'm currently 15 months out from taking 2 pills of Bactrim and it was the worst side effects of my life. It started with uncontrollable anxiety and depression. I didn't feel connected with reality and I felt very confused. By the second night I was unable to sleep and that is still plaguing me. I shook the anxiety and depression within a few weeks but my sleep didn't become bearable for about 7 months and then it was still terrible. To this day I have poor quality sleep, confusion and occasionally onset insomnia.  Avoid this drug. I also had a similar reaction to Levoquin. It gets better just ridiculously slowly. Others recover within days."
