Textul original - Sârbă - Ja sam Kao sat sto kasni, kad bi trebalo da zuri,...

Can't help you with the translation in French. I can however translate it in English if that's ok? .

I'm like a clock which is late when it is supposed to be in a hurry. I'm offering pain to myself (častiti lit. means 'to treat' someone, giving it as a gift). That virus is in my blood.

That's Okay, Thanks a lot!

De rien !
