Help!

Last Monday I swallowed a small amount of someone else's stool in an attempt to recolonize my bowel with bacteria. I think I'm now in serious trouble. I have been suffering extreme anxiety, insomnia and elevated heart rate the last few days. The anxiety being the worst symptom. Although I am worried, the anxiety started by itself, and is not simply a product of my worrying. I wasn't worrying before the anxiety started, and not even for the first day or so, only now am I worrying. I believe the anxiety is a symptom of an infection. It doesn't seem to respond to any relaxation techniques. I took a proton pump inhibitor prior to swallowing the poo, so I may have infected my stomach. It also feels like I have gastritis.

I think I have caused an overgrowth/infection of bacteria in my upper GI tract, my oesophagus, stomach and small intestine. I am scared out of my mind. I have been battling candidiasis for the last year brought on by Antibiotics . The last thing I want to do is take Antibiotics , but I'm at my wits end. I am thinking lots of suicidal thoughts. If it is bacterial infection I probably need to take Antibiotics sooner rather than later. But I don't want to take antibiotics unless I absolutely have to.

What should I do?
