herkese mutluluk oyunu oynamaktan býktým sensiz hayatta anlamsýz her an kalbimdesin seni hayatýmýn sonuna kadar seveceðim bunu unutma meleðim

thanks

My try:

I´m tired of pretending I´m happy. Without you life is meaningless. You´re in my heart every moment. I´ll love you till the end of my life, don´t forget that, my angel.

To prevent comments: i thought "I´m tired of with playing this ´happiness-game´ to everyone" could better be translated as "I´m tired of pretending I´m happy".
