hey there, i'm sorry you're going through such a bad time with hh. to be honest, i know how you feel, it can be so frustrating/depressing/enraging!!
in regards to ur work issue, i really think you should discuss it with ur boss but in a FORMAL setting! that way he/she will have to deal with any office bullying you may face. it is outrageous that you would be forced out of jobs because of hh.. if it was any other disease and someone faced workplace bullying/discrimination it simply would not be put up with, so why should we have to deal with being humiliated for hh. it is a disease like any other! so make it clear to your boss that it is a medical problem, and that you have had problems in the past, and im sure it is their (legal and moral!!) duty to accomadate you!
hope this helps some, and hope ur feeling better! x
