Trying to figure out how much ck I can do in a day without frying myself again

I am in this awkward place where i know i need to take ck seriously, but i also know what happened the last time i treated an exam like it was the only thing that mattered. i pushed too hard for too long, ignored every red flag, and then spent months feeling like my brain was made of wet cardboard. i am a little scared of repeating that. right now i am experimenting with something that feels smaller than what people usually post here. on most days i pick one solid timed set and commit to actually understanding a handful of the questions i miss. not every single detail, just a few where i can see the same pattern popping up. if i have energy after that, i might add some focused reading or another short set, but i do not write that into the plan. i also tried moving my planning out of my head and into something i can see. i sketched out the next few weeks, marked the days that are already heavy with rotation or life stuff, and then fit study blocks around those instead of pretending every day is blank. i dropped that into a basic planner so it is not constantly being reinvented. in my case that happens to sit in oncourse because someone showed it to me, but a notebook would do the same job. the point is that i can look at it and say this is enough for today instead of arguing with myself all night. i still worry that i am doing too little. i also know that the version of me who tried to do way more did not actually end up learning more, they just ended up exhausted and numb. i am trying to trust that a consistent, slightly smaller effort might be a better trade this time around. if anyone has managed to prep for ck while still being gentle with themselves, i would really like to hear what your days looked like in practice.
