What is love

The feeling that won't go away
Sometimes it feels like I'm walking astray
Sometimes it feels like I shouldn't stay
But then this is the first time I'm feeling this way

At a point I thought I was sick
Started losing weight I felt I couldn't stand to my feet
My head was noisy I couldn't think
I thought to myself maybe this is it

Unfortunately, she looked at me but she couldn't see my pain
She looked at me smiling but she couldn't see my heart dying
She looked over but she couldn't see my trying so hard to breath

Still, all I wanted was to forgive her
All I wanted was her approval
Even when I knew her mind was afar
I wanted to buy the lover she was willing to give to him

What is this thing that makes me so weak
What is this feeling that makes me want to be with her
What is this feeling that won't go away even though all she treated me unfairly
What is it that they call love
