I'm back on BactrimDS again. They found blood in my urine again. Seems like it's never ending. Just so tired. I'm extremely exhausted. Both from the infection running me down and from the emotional exhaustion of always being sick. I have to do 14 days of the Bactrim and come back for more test. They said if I come back with blood in my urine again I have to go for a bladder biopsy. I'm just lost and numb to it all. Just so tired I can't think.
