Wow, I have this problem too. I haven't been diagnosed with anything, but Im always late for school, slower than everyone else and cant keep up either. I am always distracted and will do anything to get away from the work. I try to keep up but once I cant take it I stop...for a REALLY long time. I am currently in high school, my last year and I am in danger of not graduating. Maybe its the ADD combined with depression and stress that makes me unable to do the work required. I could graduate early if I tried hard enough but I just cant. I don't know why. so maybe you just get stressed? your mind is elsewhere? scatter brained? ( im like this. so thats why i mentioned it.) My mind is all over the place so I always forget things. Maybe you just get stressed and when you see things like " Needs to improve" it sticks to your mind like glue. So when you try harder you mess up because your worried you will mess up. I think its more paranoia or a certain mindset that has got you down. It might just be that and you need help to change your mindset.
