Yes!! I do these all the time all the time. I actually gave myself (met the criteria for) an eating disorder on accident (arfid) because I was always so uninterested in food or just not hungry. It is also just daunting like you said. Trying to figure out what textures or flavors to eat and then spending time making it or going to buy it and then dishes most of the time.
A good tip for that is trying to prep meals. There are so many good easy "one dish" recipes and once you start on one meal maybe you'll get into a groove and you can cook some more to save for the following days. Another thing is buying fruit (pre cut so it easier) and then prepping fruit salads in small containers so you can just grab it and go.
As for the pee thing, I totally get that and I know it's really bad for your bladder to hold it all the time. So something that kinda works is getting into a habit of going to pee after the 2nd or 3rd wave of that feeling.
Idk if everyone gets that but it's like a wave of having to pee rly rly bad and then it goes away for a while and then come back way worse.
