Is it my anxiety making me worry

Hi! I had a job interview last Wednesday and by the end of it she said she would like to offer me a position and that I would be emailed about all the details. She said the training would be on the 24th which is next Monday (it’s currently Monday 17th) and I still haven’t had the email. My anxiety is making me worry that I haven’t had the job and that they’ve changed their minds.. am I being paranoid? I know I’ve got another week to go but I’m just worrying myself sick. Is it all in my head?? Any advice would be great. I know I probably sound stupid so please try not to be too harsh lol
