Tagalog Speakers, Could You Translate This Song For Me?

Heto ka na naman (here you are again)
Kumakatok saking pintuan (knocking at my door)
Muli naghahanap ng makakausap (looking for someone to talk to)
At heto naman ako (and here i am again)
Nakikinig sa mga kwento mong paulit-ulit lang (listening to the same stories over and over again)
Nagtitiis kahit nasasaktan … (i am just persevering even though it hurts)
Ewan ko bakit ba hindi ka pa nadadala (i don’t know why you did not go along)
Hindi ba’t kailan lang nang ika’y iwanan nya (is it not that it was just a while that he left you)
At ewan ko nga sa ‘yo (i don’t know with you)
Parang balewala ang puso ko (as if my heart doesn’t matter to you)
Ano nga bang meron siya (what is it that he has)
Na sa akin ay di mo makita … (that i don’t have)
Refrain:
Kung ako na lang sana ang iyong minahal (if i were the one you love)
Di ka na muling mag-iisa (you will not be alone again)
Kung ako na lang sana ang iyong minahal (if i were the one you love)
Di ka na muling luluha pa (you will not shed tears)
Di ka na mangangailangan pang humanap ng iba (you will not have to look for another)
Narito ang puso ko (my heart is here)
Naghihintay lamang sa iyo, oh-oh-oh …(waiting only for you)
Heto pa rin ako (i am still here)
Umaasang ang puso mo (hoping for your heart)
Baka sakali pang ito’y magbago (maybe you will still change)
Narito lang ako (i am only here)
Kasama mo buong buhay mo (your companion thru life)
Ang kulang na lang (the only thing lacking)
Mahalin mo rin akong lubusan … (you love me all thru out)
(Repeat refrain)
Kung ako na lang sana, oh-oh-oh.. (if it was only me, o o o)
(Repeat refrain)
Kung ako na lang sana …(if it was only me…)
