Good luck with your interview. Sorry to hear you’re not feeling at your best. Are you the type of person who normally finds that interviews are easy to do and that you can take them in your stride, or do they stress you out?

It’s good that you have got to the position of securing an interview - that in itself is an achievement. If you can secure one interview, then you can secure another, and sooner or later you’ll find a way out of your current unhappy work situation.
