Hi, my problem is that whenever I need to go somewhere that I consider stressful of anxiety inducing place for me, I get diarrhea before going. For example going to dentist, massager or even work. Like 99.9% of the time it happens. It's so common to me that two weeks ago when I was about to go to massager and I didn't get it it felt really weird and I was worried it would happen at the massager. 

Anyway I have been studying and working remotely for two years now, and in a month I'm supposed to start at a new job as a trainee and it's not a remote job. And I already know I'm going to have diarrhea every morning before going there and I just can't handle it. Last time when I worked "non-remotely" I also had diarrhea every single morning before going to work and honestly I can't handle it again, it was so awful. 

Does anybody have this same issue and/or have you found a way to stop it from happening? 

I recently read here about someone throwing up every day before work, I guess this goes to same category. As emetophobe I'm glad it's this way for me and not vomiting but still I'd like it to stop
