Darija Translation of English words

Salam…I am an Indian author & penning down a novel, where there’s need to use Darija, as the protagonist travels to Morocco…hence would love to get certain English words / sentences translated into Darija…Thanks in Advance!!

Give me the Darija word for "Disappointment"

Can I have the context? To express disappointment or that something is unfortunate we say “khsara” which means “loss”.
