Why do we feel? How do I stop?

Why do we not take away the pain
But then those in pain cannot
And pain for purpose to warn
But what if the harm is only the pain itself
If what is bad is only that it hurts?
It wouldn’t matter that he doesn’t love me if it didn’t hurt
I don't know what love is anymore,
So I drink
Pretty alcoholism for the ache

Strength? Or masochism
Sacrifice? Or emptiness
