Anguish!
It was certainly a sense of anguish because it felt worse than just pain. And this anguish was slowly starting to rule inside Xiu's heart. Her head was pounding just a moment ago but now, she felt extremely light-headed.
She felt stuck in a helix which was slowly turning as it unraveled the feelings and memories that didn't belong to her. Her mind was slipping through the gap of emotions and she felt like drifting and drifting and drifting away. Or was she really drowning?
She wanted to breathe and yet she couldn't catch her breath. The darkness was threatening to swallow her whole. And just when she thought she'd lose herself to this overwhelming feeling, someone held her shoulder and shook her violently.
"Oi! Look at me! Why are you scaring me?"
