I remember the sound of my sister's epileptic seizures

I had a younger sister when I was born. When I was 3 years old. My sister died painfully in the house. What I remember is hearing the sound of her seizures while she fell to the ground. I remember hearing epileptic seizures and sounds of pain. I painfully remember the day she died. I was 3 years old and remember every sound. I still remember the sound of her painfully dying. It still haunts me.
