I Have Attention Deficit Disorder (ADD)

Have you ever screwed up something simple just because you were not following directions and then get mad at yourself for screwing up something so simple? I was trying to cook something earlier and managed to screw it up twice simply because I wasn't following the directions perfectly. I was determined to get it right so did it a third time and it turned out fine. I always feel stupid when I mess up something simple like that. My therapist keeps trying to get me to go easier on myself.
