salvation for fickle heart

You were a rainbow for my rain.
Remedy to my pain.
Though we have chosen to go our separate ways.
I have returned to my self-pity cage.

I am afraid of what it has done to me.
I get lost in thoughts, and it is hard to get out of it.
Sleepless nights and these red blurred eyes.
Made me realize that you were my shining knight.

I didn't mean the thing that I had said to you.
Though I probably don't deserve it.
Please forgive me and take me in with you.
Give me a chance to make it up to you.
