Oh, @dumphies21, so very, very sorry for your loss. 


Yes, perhaps a bit more time off would have been better; but for today, you're commited to the meeting.
I have learned the "push back" thing:
when you start feeling a surge of grief, just tell yourself, "ok, I will just hold off until after the meeting (or after I get home), and then I can fall apart as much as I want!"
It actually works, to some extent.
And one of the best little gems of advice I was given long ago is,
"Just take deep breath and do it."
Also, you may surprise yourself!
At no time will the situation be "great", but you can still do a great job.
And afterwards, yes, it might be best to ask for a bit more time off.
It really, truly sucks, @OP, but try to block it for just a few hours today.
Let us know how it goes.
Someone is cheering for you, from here Japan!
