I would ask yourself if your personal statement fully answers the prompt. I ask because I've read a lot of PS's that stray from what they are supposed to be talking about, and because it's pretty hard to keep things short enough and I wonder if you were able to fit the full answer in while also fitting in all that other stuff. If your PS does not address the entire prompt, then transfer most of the diversity stuff over to the appropriate secondary essays and make your PS more focused on why you want to be a vet, your understanding of the field, etc. If your PS does answer the prompt appropriately while also touching on the diversity stuff, you could choose to go more in depth about something on the diversity essay or find something completely different than your non-trad status to write about for the diversity statement.
