gülmemiz gerek translation please

hi guys
can u translate this song (gülmemiz gerek) pleaseeeeeeeee
Ne yapalim demekle olmuyor dostum
Artik caresini bulmamiz gerek
Bizi bize düsman eden insani
içimizden cikarip atmamiz gerek

Duygumuz aynidir inanki dostum
Katila katila gülmemiz gerek
Bitsin artik yasimiz bitsin acimiz
Bambaska yarinlar kurmamiz gerek
Bize bizden baskasi dost olmaz dostum

Var olan gercegi görmemiz gerek
Sebeple kavgaya kimimiz kime
Kanayan yarayi sarmamiz gerek

Duygumuz aynidir inanki dostum
Katila katila gülmemiz gerek
Bitsin artik yasimiz bitsin acimiz
Bambaska yarinlar kurmamiz gerek
Bize bizden baskasi dost olmaz dostum

GÜLMEMİZ GEREK
WE SHOULD LAUGH

Ne yapalim demekle olmuyor, dostum
IT WON'T WORK TO SAY "WHAT SHALL WE DO?", FRIEND
Artik caresini bulmamiz gerek
WE SHOULD FIND THE SOLUTION OF IT
Bizi bize düsman eden insani
THE PERSON THAT MAKE US BE ENEMY TO EACH OTHER
içimizden cikarip atmamiz gerek
WE SHOULD DİVEST (HIM) FROM OUR INSIDE

Duygumuz aynidir inanki dostum
OUR FEELING IS THE SAME BELIEVE FRIEND
Katila katila gülmemiz gerek
WE SHOULD BE IN STIHCHS
Bitsin artik yasimiz bitsin acimiz
LET OUR MOURNING END, LET OUR PAIN END
Bambaska yarinlar kurmamiz gerek
WE SHOULD SET UP QUITE DIFFERENT TOMORROWS
Bize bizden baskasi dost olmaz dostum
NOBODY OTHER THAN US CAN BE FRIEND FOR US, FRIEND

Var olan gercegi görmemiz gerek
WE SHOULD SEE THE EXISTING REALITY
Sebeple kavgaya, kimimiz kime *
REASON AND FIGHT, WHO OF US TO WHOM
Kanayan yarayi sarmamiz gerek
WE SHOULD BANDAGE THE BLEEDING INJURY

Duygumuz aynidir inanki dostum
OUR FEELING IS THE SAME BELIEVE FRIEND
Katila katila gülmemiz gerek
WE SHOULD BE IN STIHCHS
Bitsin artik yasimiz bitsin acimiz
LET OUR MOURNING END, LET OUR PAIN END
Bambaska yarinlar kurmamiz gerek
WE SHOULD SET UP QUITE DIFFERENT TOMORROWS
Bize bizden baskasi dost olmaz dostum
NOBODY OTHER THAN US CAN BE FRIEND FOR US, FRIEND

*This is a strange sentence, I couldn't understand it.
**We should heal the injury (pain) in our inside.
