Tradução - Turco-Inglês - Yanıldım ah ziyan oldum.

I was damaged...> I was wasted.

At least in the UK (and I think in the US too, but I am not sure) 'I was wasted' is something someone would say if he / she was very very drunk. I don't think that is what was meant here

Could it be something like 'I went in vain', 'I went for nothing'? (may very well be completely wrong - I got this from google which is usually awful for Turkish translations )

I think the translation is ok.

hi Lein,
the exact definitions of 'ziyan olmak' are 'to go for nothing', 'to come to naught' and 'be wasted'.

since one of the definitions of 'damaged' is 'to have a bad effect on someone in a way that makes him/her weaker (or less successful)', it'd be ok to use 'damaged' here.

OK, thanks!
