I’m sorry that you are feeling depressed. I can relate to how you are feeling. I also have no friends, don’t get along with anyone in my workplace and get depressed from the challenges of ADHD. We are here for you. Are you trying to look for a psychiatrist or MD that can diagnose you? You can try the directory in the Additude and Chadd website. Maybe you can also call the psychology department of colleges or universities near you and ask if they have any doctors specializing in Adult ADHD?
Take care and remember that you are never alone
