"You were my best friend, my everything. The best mother a daughter could ever ask for and I'm so grateful to have had a mother like you.

"You were the most kind, sweet, loving, giving, and caring soul. You had the biggest heart.

"And I don't know how to go on without you. It all happened so quick [and] I wasn't ready for you to go.

"An angel was sent to heaven on March 18th, 2024. I love you mommy and you will forever be missed."
