I was never my mom's favorite child. It was always her and my sister.

When I was old enough to be on my own, I left without looking back. I made my own way in the world, had a family and built a beautiful life. But a trip to the emergency room in 2013 changed everything. My mom had dementia, and I was tasked with taking care of her, all by myself.

I learned everything I could about grief in an effort to prepare for her to die. I had to face my own resentments, fears, and anger as I accepted my caregiver role so I could love my mom while she was alive and dying.

Even at the end, when I was just a nice lady to came to visit her, I was ready, no matter how many years she had left. I knew I'd be by her side and hold her hand as she left this earth. But nothing I did prepared me for what actually happened.

All my best-laid plans crumbled around me as I had to use everything I'd learned to make it through the worst thing I could never have imagined.
