omur boyusevcem nedenmi senisenden cock sevdim unutma seni bi omurboyu beklicem 

ayda bana 2 dakani ayirsan cokmu dostcakonusurvz ama olene kadar kalbim aciyack 

Dunyada tanidigim en iyi insansin dostum sesini duymak istiyom birazda olsa 

mutlu edersin bu cani

My attempt at the first part:

Ömür boyu sana mutluluklar dilerim.

I wish you life-long happiness.

Bir gün aðlarsan mutluluktan olsun,

If you cry one day, may it be from happiness.

ama seni bir ömür boyu seveceðim.

but I will love you (for) a lifetime.

Dunyada tanidigim en iyi insansin dostum sesini duymak istiyom birazda olsa 

your are the best person that iI have met in this world I want to hear your voice my friend if only for a little

 nedenmi senisenden cock sevdim 

why is it I loved you more than you loved me?

ayda bana 2 dakani ayirsan cokmu dostcakonusurvz

is it to much if you call me twice a month for a friendly conversation

my try

And leaving the tricky middle bit for someone better, my attempt at the last bit:

ama ölene kadar kalbým acýyacak

but, until you die my heart will ache.

Dünyada tanidiðim en iyi insansin dostum.

My friend, in the world you are the best person that I know.

sesini duymak istiyorum

I want to hear your voice

biraz da olsa 

even if it is just a bit 

mutlu edersin bu caný

you will make me happy in this life. 

Ah deli, I´m a bit slow, but its good we agree on the words,

Punctuation would help, and we differ in where we put ´my friend´.

well yours is probably the correct placeim not good with/at putting things in the correct place

I´m not sure who is correct.

Nice work deciphering and translating the middle section. 

Missing letters and no punctuation was going to make it very hard for me. 

why thankyou kind sir

And the whole piece, with deli´s help:

Ömür boyu sana mutluluklar dilerim.

I wish you life-long happiness.

Bir gün aðlarsan mutluluktan olsun,

If you cry one day, may it be from happiness.

ama seni bir ömür boyu seveceðim.

but I will love you (for) a lifetime.

Neden mi seni senden çok sevdim?

Why is it I loved you more than you loved me?

unutma seni bir ömür boyu bekliyeceðim

Don’t forget, I will wait a lifetime for you.

Ayda bana 2 dakika ayýrsan çok mu dostça konuþuruz

Is it too much if you set aside 2 minutes for a friendly conversation

ama ölene kadar kalbým acýyacak

but, until you die my heart will ache.

Dünyada tanidiðim en iyi insansin dostum.

My friend, in the world you are the best person that I know.

sesini duymak istiyorum

I want to hear your voice

biraz da olsa 

even if it is just a bit

you will make me happy in this life.
