You will get people who don't understand. If that is zapping your energy to respond then stick to responding to posters that you feel do understand/do get it. This will be more helpful. (If anyone reading is curious, not judgemental, about how people get into a very messy state - I'd suggest to start a new thread, not use this one).
I'm glad that posting the photo helped before and it was a good idea to repeat that because it helped previously. But I still think this could be framed in a different way, not shame, more, solidarity? Accountability? It's just about having that input from others, people saying yes, keep going, you're doing really well. Before and after photos can be good. But you can also post without the photo and hopefully get the support too.
Remember that some people responding saying it's still bad didn't see your previous post and the progress you've made there.
I agree that it would be a good idea to seek some support for mental health/query neurodiversity. You have kids with SEN, it's not unlikely you'd be neurodivergent yourself (unless their disabilities are known to be genetic, de novo, caused by an external event eg prematurity or birth injury). But either way, it's hard raising complex kids especially on your own. Especially in the UK as the support is so non existent and nobody is set up to deal with you, so even the support that is in theory available to other parents is often a dead end. That's incredibly hard, it's not you failing, it's a crap system.
Having no energy is not a stupid reason not to be able to do things. It's a very real and difficult challenge. I'm glad to hear that you're pursuing blood tests as if some kind of issue is identified here that can be helped, that will be a little bit better. It's really difficult when you have multiple challenges that all stack on top of one another because it makes everything harder. And then you get behind on things and that makes everything else harder. The majority of people have no understanding of this which is what makes them ask questions like "but how does it even get like that to begin with?" Or give advice that assumes that those challenges aren't present.
Your other example of a "stupid reason" - bin is full so can't put things in it - again same issue, and not stupid. Never think something is stupid, just because the majority of people don't have that problem. Something that I had to realise for myself, that most adults apparently intuitively know or perhaps learned as children, is that there are tasks which need to be done no matter what because they are blockers for other tasks. Bins and washing up are examples of these tasks, so it's now sort of my marker of bare minimum, for the days that I need that. Also food shopping. I somehow had the food shopping down, but not the others. The "How to keep house while drowning" book is excellent on this kind of thing. The example she used was that dirty dishes would pile up and up and up until she was overwhelmed, until one day she realised that she could put dirty dishes in a dish drying rack, to store them until she was ready to wash them, and this small change, that would never occur to the majority of people because the majority of people just deal with their dirty dishes, changed how she was able to approach that task, which had a knock on effect elsewhere because that particular task is a blocker.
That kind of thing is what I mean by looking for the barriers. When you're looking for a barrier, it's not so that you can beat yourself up and think God, I'm so ridiculous, I can't even do this simple thing, I'm hopeless. It's so you can look at it and try to see it neutrally as a problem which might be able to be solved, avoided, worked around, or supported. That is how you move forward and make progress when progress feels impossible.
