Im in a rough spot msyelf. I've been on ritalin and concerta m whole life for severe add and adhd but it affected my mood too much so i've been on and of of it. The weeks that im on it im miserable, have terrible headaches, but am incredibly productive and confident in my work. The weeks when im off im happy and stupid, and all of my activities blend in to a mush nof a waste of frustrating time. This isn't smething you can get over, you have to go see someone and get help
