Are you immune-suppressed? Usually, people with normal immune systems do not get C. Diff. The stuff on your tongue is likely fungal; have you had it tested in the lab? The fact that you have Clostridium Difficile AND what sounds like an OVERGROWTH of Candida Albicans say that your immune system is not working as it is supposed to. If I were you, I would get another stool test a few days after you have completed the 2-week course. I picked up a case of C. Diff in the hospital and it took 3 courses of Vancomycin to get rid of it. Don't worry about infecting others unless they are elderly, newly-born or otherwise have abnormal immune function. How would you lose your job? Hopefully, you can be honest with your employer. You picked up a disease and you can get a letter from a physician which attests to that fact! You may be anxious and cry daily if you wish but, frankly, I would suggest that you educate yourself with regard to C. Diff , Candida Albicans AND tests to find out whether or not your immune systemn is working!! Furthermore, it sounds like you are in need of some emotional support!!!
