Had to leave work early today and feel so guilty

I got an aura today, vision was off. Then I was confused which was very inconvenient because I’m a nurse and need to think quickly.. it took me 3 tries to write a doctor’s name down as she was spelling it out for me. I can’t make mistakes so I just went home. I feel really guilty for going home and feel like I let everyone down. :( I took a nurtec when I started to feel weird so no pain, but sometimes the aura for me is more debilitating.
