I am a 25 year old female who feels like an old woman. I have been diagnosed with depression, anxiety and hypothyroidism. I am on synthroid, prozac and topomax. My problem all started a couple years ago when I got Mono. I had it for almost a year because I could not afford to take time off of work to get better. For the past 2-3 years, I have not been myself. I am constantly fatigued to the point that I cannot make it in to work at least once a week. I literally feel like I need a nap every couple hours. On top of that, I catch every virus that comes along. About a year ago, I had HPV. Several months ago, I developed sores in my mouth. And now.....I have a major E-coli infection. Plus, the sore throats, colds and stomach bugs never end. I've seen every kind of doctor imaginable and they all tell me, "your tests were negative....your fine". I'M NOT FINE! I HAVEN'T BEEN FINE FOR YEARS NOW! I know there's something wrong with me but I don't know where else to turn. I truly believe there is an underlying cause to all the viruses/sicknesses I catch. There's gotta be something the doctors are missing....but if they can't find it, how can I? Can anyone offer any ideas or suggestions? Please!!!
