Hello! Some family friends of mine left me a message on my birthday...but I don´t understand it. I was hoping someone could help me!

benim sevgili en iyi arkadasim iyi yilar iyi yaslar mutlu ol her sey gonlunce olsun
yildiz, murat, ekin, dogac. (I know these are their names! haha)

benim sevgili en iyi arkadaşım iyi yıllar iyi yaşlar mutlu ol her şey gönlünce olsun
I will try to break it down for you, but I am also learning

benim = my

sevgili = dear/beloved

en iyi = best (most good)

arkadaşım + my friend

iyi yıllar = good years

iyi yaşlar = good times (not sure)

mutlu ol = be happy

her şey = everything

gönlünce = after one´s own heart, to his/her heart´s content

olsun = let it be

So my try is ..... My dear best friend, may there be good years, good times, happiness and everything to your heart´s content  

 my try

benim sevğili= my dear

en iyi arkadaşim = my goodest friend

iyi yilar = good years

iyi yaşlar mutlu = good and happy life

 ol her sey gönlünce olsun - not sure about that but its a wish coming from the heart

Oh.. sorry about that. i am always taking my time in translation.  

thanks Henry

Don´t be sorry, we all learn by trying.

In English we don´t say "goodest", we say best.

Good, better, best, (English) iyi, daha iyi, en iyi (Turkish)
