This Shady Thing Called Past

Often I encountered strain
With this shady thing called Past
My vulnerable brain
Was about to have a blast

It stirred my focus at work
I felt exhausted at home
The feeling of being stuck
With consequences to come

So I had to find a cure
A permanent remedy
So I opened up the door
Of my brain quite readily

In the corner there I locked
My disturbing past forever
Hid the key then blocked
Its exit to wherever

And once that it was done
I felt happier and free
Applauded my decision
Brewed myself some tea
