Replying to Greatest accomplishment?

The feeling of accomplishing something or someone is a feeling and sensation like no other, an overjoyed feeling, centrally aroused and happy with butterflies.

For me, it was playing a piano recital at the prestigious music hall. However, I had extremely bad diarrhea so I tried to go to the bathroom beforehand, but my Russian music teacher wouldn't let me go. I was very nervous and scared that I would poop my pants. When I was introduced I walked quickly over to the piano and sat down. I swiftly turned my butt so that it was facing sideways in view of the fact that if i did poop no one would see it and I would have a clear, secluded run to the bathroom. When I started to play all i thought about was the holding in of the finicky feces which was urging to come out, However, I played through it all with little to no mistakes and by finishing and facing my fears I felt confident and accomplished.

One of the worst moments of my life and one of the best.
Another bad moment was when I got testicular torsion.
