I hope the hospital can help resolve or minimize the problems you're having. It wouldn't be safe for you to try to work in most places as long as you are having seizures or losing your balance like that. Good luck on your recovery.
If the manager isn't in, you can ask for a job application form to fill out, either there or at home. As for interview questions, there are books on how to interview that have sample questions. Your mother could do practice interviews with you using the book as a guide. There are also interview ideas on previous WrongPlanet threads.
