I am not feeling so good

I am not feeling so good as I made a mistake
A mistake so big that you did not react
If I may ask one thing from you in life
That would be forgiveness my friend
It is pure from my heart you may know
And it is pure from my mind
Things that I want to change
Things being unkind
Life gives new reason to everyone
So won't you give a chance to me
It's all I want to see
It's all that I am wanting to see
I ask for forgiveness my friend
Only from you
I hope you will understand!
