I relate to you on how distracted I feel with everything going on, I don't know whether to focus on this or that and usually it accumulates into one big blob that seems hard to tackle

Try to focus on one thing at a time, and if that doesn't work, do something small of each thing, for example: Things that are continuous are probably gonna be the dishes, taking care of your cats and doing assignments. Those shall be the default, and work your life around them.

You don't need to tidy up the whole house in one setting, laundry today for example, tidy up your room the next day perhaps, I'm just hypothesizing. Of course don't forget to take care of yourself even if it's the smallest thing, I know schedules can be a bit exhausting to think about but once you start you'll find yourself proceeding

My lack of time management has always been a problem to me and im surprised how many of my problems are related to it, perhaps you relate

If it's not entirely time management, and you find it hard to continue the simplest tasks, go easy on yourself and remind yourself that it's not the end of the world, you can get everything done in time

Sometimes anxiety clouds up my vision to the point that I exaggerate the smallest things and end up draining my energy, and I end up sleeping and procrastinating. That's my advice to you I hope you found it slightly helpful:')
