I am of the belief that your depression, your ADHD, your messy divorce, your whatever the fuck else is happening outside of work should not be discussed with your boss, with HR, with your coworkers, or anyone else at work. These people are not your friends and they will never use this information to help you, only to hurt you. It's not school, your boss isn't going to give you an extra 30 minutes on the final exam, they will only use it as a thing to point to if there are problems. Protect yourself.
