After traveling for 36 hours, I felt achy w chills and slight fever. That is gone, but now I am very nauseated. I vomited and now my r ear hurts?

Earache. Sounds like the flu and/ or earache.
Will likely need to see a Doctor for an otoscope exam of the ears.
Rest if you can, try to keep fluids down. Can use Tylenol if you can swallow it at the moment.
You may feel awful but your young and probably healthy so you will get over it faster.
