You may say I'm a pessimist.

Some scared about the future

Some scared about the past

But I'm scared about the future and the past

For the future I am too blind to see

And the past I can never ever fix.

You may say I'm a pessimist. I am, in this case. How can you be so sure that your good deeds have been accepted and your sins have been forgiven by Him? I left you to think it over...
