A Letter Of Goodbye

How do I blur this picture I'm carrying?
How do I sound like I'm caring?
I wish I should've told you before,
But I didn't know the right words to look for.
For regretful days and helpless nights I'd say I will,
But my anxiety was in another level.
I'd understand if you called me naive,
Because there's nothing less I deserve.
A year of work without you is worse than a lifetime seclusion,
And now I regret with passion,
Not enjoying our last moments with you,
Only because I couldn't say adieu!
