No career is a good or a bad fit for all ADDers. Restaurant work certainly is chaotic and stressful, but your passion for cooking is the most important aspect of choosing this career. I’ve seen ADDers thrive (and fail) in a variety of careers. What is essential for you to do is to define your strengths and weaknesses.
For example, if you are not good at tracking inventory, but great at planning daily specials, you’ll need to discuss this with your future boss. When you’ve landed a job, strive to get better at those aspects that you struggle with. For instance, you may need to develop your own accommodations, like getting to work in time to organize your cooking station before your shift begins.
Also, remember that there are many different kinds of jobs in any field. A large, busy restaurant may, indeed, be too stressful for you, so consider starting off at a smaller restaurant, or working for a catering business.
