Welcome Ayana Walker,
I’m sorry to hear that you’re unable to locate your projects, especially since they contain important schoolwork and manuscript notes.
Since you confirmed that you sign in to Copilot using your school credentials, this involves a work or school account rather than a personal Microsoft account. Work or school accounts are managed separately, and their Copilot experience can also depend on the licenses and settings configured by the organization.
I recommend contacting your school’s IT administrator or Microsoft 365 administrator so they can check your account, licensing, and Copilot access.
Please avoid sharing your school credentials or other private account information in this public forum.
Thank you for your understanding.
