See what she said inside…

“Dear Mommy, I can’t believe your gone. This doesn’t even feel real. I keep hoping that I will get to hug you or kiss you or hear your voice one last time. 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,” Natalie wrote.

“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,” she continued. “It all happened so quick & 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. 😔💔”
