How to be empathetic in the mortuary field when you don't experience grief?

I think validation is always a safe alternative to give. I have the same problem in expressing those emotions (and really any emotion others expect empathy with lmao). so instead of trying to "comfort" the families/friends, you can offer phrases of validation such as "I understand nothing I say can take your pain away". then just maybe add in a general condolence at the end or something. it obviously depends on the person, but most people I've known liked to have the potency of their pain validated. honestly I think expressing an understanding of your LACK of understanding is appreciated. it's not something a lot of people even know they needed/wanted to hear since it's an uncommon thing to express.
