Your boss just died(? probably? But they also seem to like to pretend they've killed people they haven't.). Can you take a day off to process? No one sane would expect you not to be shaken.
Come up with them and tell Priya and I and we'll keep an eye on you.
But this is also your job. I can't say yes, you should definitely quit because I'm still here despite everything. At least with you there, someone is actually trying to do the job properly.
