Needing to preserve my OD

I haven’t updated this diary in forever, but the early years that are covered in here are very important to me. They show how far I’ve come and how far I fell. I see that OD is completely shutting down as of 1/31/2026. I’ve tried contacting them to download my diary for me as they claim they would, but never heard anything back. Is there a way to preserve my diary and even the comments to the entries?
