Перевод - Сербский-Английский - Znam da je tesko al nemogu da izdrzim ovako ja cu...

The French would be in English:
I know it's difficult, but I can't stand it anymore. I'll give it back to you. I'm sorry to ask this of you, but it's really a crisis.

But I still don't know what this means...?

"de te demander ça" = to ask you this

Of course I can be
wrong, but I would say:
I know it's difficult but I can not stand it like that. Iwill render it to you. I am sorry to ask you, but it is really emergency.

ja znam daje to tesko ali ja ne mogu da izdrzim ovako.Ja cu ti vratiti nazad. zao mi je da trazim od tebe, ali je velika kriza

"da ti trazim" = to ask from you

Hi

Basing myself on the French translation the following phrase (which seemed quite faltering) needs changing:

"I am sorry to ask from you, ..."

It should read:

"I'm sorry to ask this of you"

or

"I'm sorry to have to ask you"
