Thoughts That Grow

Am I obsessed ?
Paranoid ?
I must confess 
I’m not too sure.
For my brain,
Dopamine deficient
Can take a thought 
Be it wrong or right
Like a seed
And cultivate it
Feeding it 
Growing it
Breathing life into it.
Too scared to let it out
It takes on a life form
Of its own
Before I know 
It has branches 
It has leaves
My initial thought 
Has turned into 
A tree.
What a terrible disease!
For what now?
Do I still feed it 
Give it what it 
Still needs ?
Or try to 
Save myself 
Break the curse 
Cut down the tree
And kill the thoughts,
That are killing me.
