When you say you have to run to the bathroom, what do you mean? To throw up or to have a bm? I agree that it could be anxiety related, but I would want to rule out an underlying medical issue first. As for some diva being more aggressive than others, I think that's true. But I also think it's true of patients. It pays to be proactive and assertive. For instance, given that your mom has thyroid issues should be something that you've discussed with your doctor in terms of what additional annual screenings are appropriate for you. My sister has a thyroid-related autoimmune disease so I pressed my doc years again to screen me for that.
