TF, from TDK to All Mine, PET always

[KuaiLe]

I read this from the Acknowledgments in After the Breakup: A Self-Love Workbook by Tamara Thompson LMFT. The author expresses her gratitude to all her family members. And then it goes:

My exes, thanks for the lessons. My beautiful friends, I appreciate you. TF, from TDK to All Mine, PET always. I have gratitude for this life experience and our shared humanity. One love.

I'm at a loss about what TF, TDK, All Mine and PET stand for in this context. Can anybody explain for me?

I googled TDK, and that didn't help.

I got some interesting results for PET, but I don't think they apply here.

It's private code between her and somebody close to her. We're not supposed to know what it means.
