This study is about helping kids with frequent headaches, called migraines. Migraines are bad headaches that can make it hard to do daily activities. The study is testing two ways to prevent these headaches. One way uses Cognitive Behavioral Therapy (CBT), which is a type of talking therapy, through video calls. The other way combines CBT with a medicine called amitriptyline, a pill that helps prevent headaches. The study will last about 28 weeks (around 7 months). For the first 4 weeks, participants will track their headaches. Then, for 8 weeks, they will attend six video therapy sessions. After that, there will be "booster" therapy sessions over 16 weeks. To join, participants should have migraines at least 4 days a month, be eligible for amitriptyline, and speak English. They cannot already be using amitriptyline, have ongoing serious health issues, or be pregnant.

• Study duration is 28 weeks with multiple therapy sessions.
• Two groups: therapy only or therapy with medication.
• Participants must be eligible for the medication amitriptyline.
