This was literally my husband's objection to getting medicated 😂 It helped his anxiety, then he didn't have the anxiety to get stuff done, so he thought he should just not be medicated cuz he was terrified he wouldn't have the ability anymore without the anxiety.
Lucky for him I went through the same thing with my meds, but my answer was, "Use the medication to build good habits." Which is the great wisdom I passed on to him (which I probably picked up from lurking ADHD spaces before my (and his) diagnosis).
For me they help me be more ok slowing down and starting small and not feeling so overwhelmed from all there is to do. So I’m like 50% likely to do something on meds and 20% off.
They help me push past my executive disfunction, most importantly, but also to stay focused and on task.
They also kind of act as a ritual that starts a "Get it done" mindset, like taking my pill sets my intention for the day.
I had to go off my meds for a few months, and while my habits were harder to do, they weren't impossible like they felt before I had built them. I was able to rely on habit muscle memory.
If you feel demotivated to cook, clean, or otherwise leave the house. Try putting on "outside clothes" (i.e. not PJs). More often then not it will give you that little push you need to start doing the important thing
I tell myself that taking the first step (of whatever task I'm avoiding) doesn't mean I have to complete whatever task I'm avoiding. Somehow reminding myself that, for example, taking my socks off doesn't mean I HAVE to take a shower, gets me over the initial hurdle of resistance. If necessary, I will lie to myself about each step of a task, with full knowledge I'm only saying it to trick myself into doing something. At some point, I decide that I might as well finish (usually).
A funny thing I discovered, if I relax my muscles too much when falling asleep, my body's autonomous breathing stops. It's weird, I just literally stop breathing until something else in me starts to panic then I'm gasping for air.
