Oh my, the workplace can be so tough. That is such ugly and silly talk from the manager ... you have to be "better than perfect" and can't miss work unless you are dead??? Utterly ridiculous.

I agree with seesaw that if you are going to stay there you may need some backing such as FMLA or a doctor note.

Best wishes to you. I hope you find your answer soon. I know this can't be comfortable.
