en umutsuz kaldığında bir umut doğar karşına dikilir bilemezsin ki son bir umut olacağı...

My try:

I hope you know that when the last desperate hope is sewn the opposite of hope is born.

well I can say this is a problematic sentence..

but still...

"A hope borns and stands in front of you when you are total desperateness, you can´t know what´s going to happen with a last hope!?"

thanksss 

en umutsuz kaldığında bir umut doğar karşına dikilir bilemezsin ki son bir umut olacağı...

when facing new born hope youll never know what that final hope will be when you remain totally hopeless

my try ,but I think I have the words mixed up a bit

youll never know what that final hope will be ,when facing new born hope ,when you remain totally hopeless

when complete hopelessness remains a hope is born standing in front of you you can´t know that I*will be a last hope (*if ´olacağı... = olacağım)

my try a bit late
