Q / what is the meaning of the word Grudge?

a strong feeling of anger and dislike for a person who you feel has treated you badly, especially one that lasts for a long time

I'm not a person to hold grudges
But my heart can't bear it anymore

Losing yourself to a drop of grudge..?

I'm stressing myself and it's no good

The feeling of having a valueless tears

I mean meh who cares

I shouldn't
I shouldn't have spoke this way

You know why? I know why

Never trust your tongue when your heart is bitter

Unconditionally
Is the best way to love someone

Daisy, Daisy
Give me your answer do!

I'm half crazy
All for the love of you!
