At what point would you consider going to hospital?
I totally understand about how much work/study you have to do but realistically what else can your T do? He can't and it isn't his job to be there 24/7 - He can see you X times per week but if you need more than that, maybe you should be in a place that provides it. and it sounds like you are having a bad time with meds and being jerked around by drs. for the past few weeks which must REALLY suck.
But in hospital they can't ignore you and forget about you and they can see how bad it really is.
I don't mean taking months off work/intern etc but maybe a week or so. Would you fail your internship if you had sick leave for a week?

If you are this bad, you are not going to be able to do these things anyway.

What does your husband think??
