I am so sorry for your loss...and what an awful experience to receive from the hospital. Please look after yourself and take it easy. Would you be eligible for compassionate leave or something similar if you don't have any other leave available to take? After what you have gone through I don't think anyone would expect you to turn up at work on Monday morning...you do need time to grieve and come to terms with what has happened, without having to deal with work related issues as well.

Sending cyber-hugs and best wishes.
