Hi @Amandaa1,
You may not realize this, but you posted your question to the global community of Instructure product users. While we can often help with some technical/functionality questions about Canvas or other Instructure products, the members of the community here don't have access to your assignment or your Canvas instance. In this case, it sounds like your teacher may need to assign peer reviews over to you, so you'd want to reach out to your teacher via whatever method they have made available to you (perhaps the Canvas inbox, email, phone, etc) so they can get your reviews assigned.
I hope this info helps!
