Stuttering lab dub

I went to the clinic to consult my chest which is undergoing some contractions.
I was 15 back then, and the doctor evaluating me smirked at my young face.
'Let's do this,' I read her mind. She opened the drawer and lifted her stethoscope.
Directing it into my heart, the doctor recognized its high speed.. lab dub lab dub

But she was not convinced and doesn't want to believe in a young girl.
She just smiled and told me three hurting words, 'it was nothing.'
Explaining that maybe I was just nervous, perhaps dealing with heart breaks.
Heart breaks? Well, I've got none not even with my parents nor with my grades.

At that very moment sitting silently in front of her with table between us,
I badly wanted to retort, to express my defense. 'How could you?'
But I stood still, closed my fist calming myself she doesn't know, right?
I know I felt that pang in my heart, I stood up and closed the door behind her.

Six years had passed. Recalling the incident, how I went straight to the clinic,
how I consulted my aching heart, how the doctor slapped to me that it was nothing
made me realize that what she had altered is easier than dealing with heart breaks.
For I felt the same pang but this time it maybe scientific but not physically.

For I cannot go straight to the clinic and wail that my heart has been beating hard,
and I will just get disappointed by their answers that no medicine can ease the pain,
That stethoscope will just hear its fast lab dub but not see how slowly it is bleeding,
That the recovery is not inside the hospital not even outside the vicinity but inside me.

And all I can do is to close my eyes and listen to it, maybe its not just a mere lab dub,
That maybe tears flowing from within will try to wash it, to cleanse the blood away.
And I'll hear the clock's tick tock and ask myself how many times had already elapsed?
Hoping that soon enough, soon I will stand up, try to walk, and close the door behind.
