This is quite interesting, if you think about the psychology behind it. Im no expert in "conditions" or anything but i do have above average knowledge i would say. And i find it somewhat interesting how you experience things. Some things like the going back and forth seems to me like a bit of ADD while you also say you are highly focused on each task and very dedicated which seems a little like Aspergers (High functioning autism) BUT Of course only a few indicators of each, BUT it may aswell be just your personality. I dont know, I just find your post interesting. Hope you dont take any of this in an offensive way :)
