weirdly unconventional hacks from a late-diagnosed adhd girly: exercise before doing schoolwork (something quick like a run or jumping jacks to get yourself moving) the endorphins give you the doing stuff momentum but physically you’ll feel more inclined to sit down and focus because sitting is better than moving.
Also if you have long hair, tie it up tight and/or change clothes into something tighter/fancier to symbolize a shift in activity from doom scrolling to working. It gives me the same push that I would get from getting ready for work or a job and sets the tone for me to sit down and focus
