There are many things you can do to help your teenager. Start with setting boundaries and basic sanctity rules. Make sure your child knows when and how much screen time they are allowed, set bedtimes, and stick to them building healthy habits. Equip them with a planner and a digital timer so they can be strict about their daily activities. Be consistent in communicating with them - provide clear expectations, keep track of their progress, and offer help, but don't nag or pressure them too much.
