I understand. I have been there. This is where your strength and practice in boundaries maintenance is tested. You can only give what you can give. When it comes to “requirements” placed upon you, give them a time when you know you’ll have a battery with enough power to endure 1-2hr minor cleaning tasks (windows was always my choice before POTS). Inform them that you’ll only have a few hours to help, and that’s all you can manage. It’s illogical for them to tell you what you are capable of doing
If they truly want the outward perception of “wanting to help” or understand your neurodivergence, then they’ll respect your boundaries and won’t cry “excuses” when, in reality, your reasons are just mildly inconvenient for them. Be firm and detailed with what you need, if necessary. They’re struggling to deal with change (aka accepting that you are legitimately & functionally different, and not just difficult as they previously thought). Be strong!
