Hi there E-Maiky,
Thank you for posting to Apple Support Communities.
We understand you have accidentally deleted your Freeform boards. We'd like to help.
You may be able to recover them:

If you delete a board that you started and shared with others, it no longer appears on anyone’s device.
- While browsing All Boards, tap Recently Deleted in the sidebar.

, then tap Recently Deleted. - Do one of the following:
- Recover a board: Touch and hold the thumbnail or name of the recently deleted board, then tap Recover.

- Permanently remove a recently deleted board: Touch and hold the board, tap Delete, then tap Delete.
