is it okay that i’m upset ?

So basically my nanny’s cousin had past away a few days and i wasn’t really close to her and her family but i have talked to her, she’s been in my house and she always used to call the landline aswell. I just want to know is it okay for me to be really upset, i feel like i’m the only person in my family who is actually crying about it.

i know this is a stupid question to ask but i just want to know.
