I feel like hyperfixation for me but... It's more like I have a hard time focusing on my work because I feel like there's always going to be a distraction in 5 mins so it keeps me from really getting focused. This happens so much during the day that some times I find myself just trying to fill the day with menial things that aren't productive at all until everyone else is asleep and there is no possibility for distraction. It's really bad some days.
This isn't just with drawing/writing though.
This has even stopped me from doing things like playing games and such because I always have this sense of looming distraction.
