Jamie Lynn Spears is thanking fans for their support.

She recently released her memoir, “Things I Should Have Said.”

On Thursday morning, Jamie Lynn posted a message on Instagram.

She said she had “so many people to thank” for making her dream come true.

She said it was her dream to “share my own story.”

She said she was “overwhelmed by the support” to make the book a “success.”

“You’re not alone, you matter,” she added. “Your voice matters.”

This seems to be in response to a public message Britney sent her sister on Tuesday.

“I asked myself every day ‘DOES ANYBODY CARE?” Britney asked. “DO I MATTER ???'”
