Wow, I'm sorry you had to go through all that. Just a point of clarification, was being in restrained in the ICU bed due to confusion from sepsis?
Sepsis and botched operation are a separate matter from bullying/mistreated as you pointed it out it was unintentional unless there was something else to it in which case this would go to assault/etc.
Have you taken this up with your HR department or department head? There is no reason you should be being denied a chance to check your blood sugar or give yourself necessary medication. After your suicide attempt were you treated and the issues of bullying addressed? Are you okay now, or still getting ongoing treatment? How was the bullying handled? Is this a system-wide occurrence at your institute?
In terms of pregnancy, I think it depends on what policy is in regards to peripartum time off, etc. If you were expecting that they should automatically accommodate the schedule because of your pregnancy, that is often a very hard thing to do since most programs don't have spare residents to fill gaps. When I was an intern, half the class became pregnant (meaning almost all the senior female residents) at the same time. It was absolute chaos, I remember wheeling my senior down the hallways during rounds when she was in her advanced pregnancy. And yes, they pretty much kept rounding and working until it was time to deliver as well. Because if they took time off, there would be no senior residents on the floors.
Still, this is something you may want to address with HR or departmental heads. If you feel like you're being singled out or your health is being directly jeopardized (ie lack of insulin) you need to contact someone right away.
