Okay, so maybe this is me seeing what I look for, but this sounds like textbook perfectionism OCD, how that was explained to me anyway. (Though it could be a total coincidence.) I relate very hard to this, so first, *hugs* - I have been right there where you are, with the ADD and the low work ethic and the perfectionism. It’s not pathetic; it is an actual problem that tons of people have. You are not stupid or lazy or anything like that, you’re just stuck in one place.
My advice is to try and talk to some other people you know with this issue, encourage each other, do some research into techniques like ‘quick and reckless’ that are supposed to help this kind of thing. Therapy costs money, but peer support doesn’t. I’m always here if you wanna chat about it or even just yell “AAAAAAH Ene I can’t focuuuuus and I don’t waaaaaant toooooo I hate everything, I can’t even think about school because of how Big and how Much it would take and ack” into a PM. *hugs* again.
