Hello Zaza, I have some suggestions for a better translation :
1- Second line : the verb "sorulursa" is in passive voice. In this sentence there is an impersonal passive and the subject isn't "you".On the other side "cevap veremem" is in simple present tense.In this case you should translate this sentence as "if a question is asked I am not able to answer immediately "
2-Third line : By saying "girecek", the singer is speaking of her ex love.So the subject is "he" And this verb is in simple futur tense.Literally, "girecek uykuma" means "he will come in my sleep" but we should translate it "he will haunt again my dreams"
3- 4th line : Ağır yük means "heavy burden" and it is referring to "see ex love in her dreams". In this case we should translate it like this : This is a heavy burden to my patience
4- 5th and 6th line : "Bir kere girdimi aklıma" The singer is speaking of her ex love.This is a man and the subject is "he". You should translate it as "Once he comes into my mind I can't tell him to go out (of my mind)"
5- 8th line : literally, insan means "human being" But by saying "insan" the singer is speaking of herself. So the subject is " I " : Believe me I miss his smell
6- 10th line : iyi gelmek means "be good for something" or "do good". Kalbe iyi gelmek : be good for my heart (of course the singer is speaking of her own heart). By saying "sonu" what the singer intends to say is "sözlerimin sonu" or "anlattıklarımın sonu" (the end of my words or the end of what I told ) Finally we should translate this sentence in this way : But the end of what I told is never good for my heart, is never good for my heart
