hayalerımde oydu mutluydum oo varken yanımda ama akılsızca anlamsızca duygular beslemıstı yuregınde sonucta kaybetmıstım onu ama tek umutla yıne tutunur oldum mutluluga işte buda ayakta tutan benıdır ...tek umut..

thanks in advance

 I was happy when she was with me she was engraved in my fantasy ,dreams, but foolishly meaninglessly I finally lost the feelings she had cherished in her heart,    but  even  so I  cling on with a single hope ? it is me who can who can keep this alive

my try but it was really difficult without punctuation so wait for manyyyyyyyyyyyyyyyy corrections 

No punctuation and the words are not in the usual order (but not wrong).

I tried to add some punctuation.

He/she was the one in my dreams. I was happy when he/she was besides me, but he/she grew foolish and nonsense feelings in his/her heart. Eventually I lost him/her, but with one hope, I started to hang on the happiness again. And that´s the thing that keeps me alive... one hope..

well blow me down with a feather, what a mess I made of that

don´t worry, it is difficult to understand it with such a punctuation (which doesn´t exist) and word order- also some difficult expressions to translat

I am sure you could translate this better:

Hayallerimdeki oydu. O varken yanımda mutluydum, ama yüreğinde akılsızca,  anlamsızca duygular beslemişti. Sonuçta onu kaybetmiştim, ama tek umutla yine mutluluğa tutunur oldum. İşte bu da beni ayakta tutandır: tek umut.
