I arrived at Sky blah Temple with Esbern and Delphine and whaddyaknow, Delphine suddenly hates me. I've magically become the enemy and now she won't stop attacking me. I can't complete the Main Quest because I'll die, and I can'y kill her because she's essential.

Can someone PLEASE help me with this? I really want to progress past this part but I can't find a way to.
