“I woke up this morning, still half asleep, and reached for your hand. But you were not there. You left last night,” she writes in the caption.
“I don’t know where your soul went when it left your little body. I want to believe you are somewhere with my dad and my sister….and your sister…all loved ones you never met.”
A GoFundMe page was set up by the pair alongside a TikTok account to document the girl’s brave battle with the disease which gained 5 million followers.
