"i&#039;m 16 yr old female and was diagnosed with adhd when i was 6. i was on ritalin, then something else, then concerta and it was hard. i had major depression, lack of sleep, lack of appetite and the ability to feel any emotion was gone. yes i&#039;m an a student but i was not happy, so i tried vyvance. it doesn&#039;t last as long but i am happier. i can feel emotion now and i&#039;m still getting a&#039;s and b&#039;s."
