i understand the struggle. when i worked full time, i found i’d spend more hours (even after work) completing tasks, never be pain free (i suffer with chronic pain too) and the job was crippling yet i still continued! i’d then feel depressed that i never had any time and energy for things. i now am contracted to 8 hours, but most weeks work 4/5 days however not having that full-time contract feels like there is less pressure and less to commit to. also having a good team who help me switch off and leave work when the day/shift is over. i still spend quite a few days off tired and energy-less currently, but weeks where i have worked less i find i have a little more energy for the social side of life and the hobbies. i also hope that one day ill have a much better work-life balance - but it’s difficult when most of life costs money that can only be achieved by working silly hours!! i hope once you work 75% of the time, you find it easier than when you worked 100%. it’s a struggle but you will get there :) you must listen to your body though.
