תרגום - טורקית-אנגלית - Onları özlüyorsundur ama yinede kendini üzme.

Don't get upset --> don't upset yourself

That is what it said at first, but that is not really used in English.
'Don't let it upset you' or 'don't get upset' would work.

But it is not completely wrong, right?

It may not be grammatically wrong, but it is not really English either

OK, thanks.
