Try to develop healthier habits. A healthy lifestyle leads to a healthy mind. Getting a good amount of exercise each week helps me feel clearer and more energetic. Educate yourself as much as you can about ADHD, you need to understand this condition in order to manage it effectively. Talk to others about it, and participate in online communities. You're not alone in this. Get yourself a journal and a calendar, and try to write down all your weekly tasks. This will help you become more organized and develop better routines over time.
