O' Cealleigh — Love Bite lyrics

Why does love always bite?
As I approach it seems to fight
Whichever way I am never right
[ Lyrics from: http://www.lyricsty.com/o-cealleigh-love-bite-lyrics.html ]
I've cried for days, awake through nights
Lord bring the day I get it right
Why such mystery in the best things?

Pain and sadness do follow
That which brings us such joy
Why do we try find friends
Who will leave?
