Literally a huge yes to all of this but I also have another side note to add that I learned from a volunteer advocate who helped me get disability here in the UK:
First of all it’s to answer every question as if it’s your worst day, but also what they told me is that if something takes you at least twice as long (or longer) to do than the average, non-disabled person then consider yourself as just unable to do it. That’s not technically, entirely correct but it might as well be and I’ll explain why in a second.
But if you’re filling out forms for disability and check the box that says yes to “can you make a simple meal?”, then the (most likely non-disabled) person reviewing your application is going to assume that it’s taking you the same amount of time, mental and physical energy as a non-disabled person to do it. Which is untrue, so just say you can’t.
It’s also not being dishonest, it’s just a less detailed answer, even if you are technically able to do it. The answer to that question is highly nuanced and detailed and is just too complicated to explain in the tiny text box or small amount of time they give you. There are a lot of situations where you taking twice or thrice as long to do x task compared to the average person means you simply just cannot do it because you just don’t have the time nor energy available or due to external factors. In addition to this if you’re someone who for example has executive functioning issues then time spent trying to convince/force yourself to do the task contributes to the overall amount of time required to do said task, even if you’re not actively doing it.
For example, if your disability(ies) makes it so you literally need the whole day to get groceries and go to the pharmacy including waking up, getting ready and commuting there and back and unpacking what you bought, but you can’t get a day off of work/study or afford to miss a day at all to do that? Yeah you just don’t get to, you’re unable to do it. You just don’t get food and meds, that’s how that works. This also applies to people who don’t work or study because chances are that you are sacrificing doing another necessary care task in order to run that errand, usually eating a meal/using the groceries you bought.
This is also why people say it’s rather expensive to be disabled because in the case of being to in pain/exhausted to cook, you’re gonna order take-out or if you have mobility issues then you’re going to get an uber/taxi home etc. That shit adds up fairly quickly. So if you’re applying for disability that helps you with the exact costs associated with being disabled, mentioning that is actually relevant because being unable to afford those things to make up for being disabled impedes on your ability to do that specific care task.
So like… see how simply talking about getting groceries or picking up medication starts to become a really, really complicated problem and how it’s impossible for anyone’s situation to be exactly the same? You shouldn’t compare yourself because literally everyone’s situation is different, please be less hard on yourself.
There’s just SO many factors that get in the way of doing something and it’s extremely overwhelming and mentally exhausting, especially if your brain isn’t able to do prioritise tasks properly or do tasks automatically/habitually.
