I am sorry. That’s a lot to cope with. And I’ve been there, I do get it. It’s awful taking on yet another thing. And stress is likely to make it worse, too. 😏 Feel free to ignore what I’ve written below. If you have capacity though, it may be worth a look. Or you might think it’s hippy nonsense. I used to.
Products- anything you buy and use for anything. Shampoo, soap, moisturiser.
The idea is that something that’s irritating, let’s say your legs, could give you itchy skin on your tummy.
So you try and use the minimum stuff possible. Usually the GP gives you a big pot of dermol cream that you use for cleaning yourself. You use it to wash your hands, to shower, everything. You shower as little as you can. So use dermol under your arms, in your groin, on your hands and face, and then wash it off. It’s weird, washing with a cream, but it works. It dissolves any muck on the skin and lets it rinse off, while keeping your skin moisturised.
Soap and shampoo are designed to strip grease. Grease is what protects your skin. You could try washing your hair with an egg instead of shampoo. Conditioner is usually gentler, you could use that instead occasionally.
You are Stuck with using the washing powder you can afford but- try using less.
If you wash your clothes separately from everyone else’s, you could try without adding soap powder. There’s often enough residue in the machine to do a load- assuming you don’t get particularly grubby. I work from home and don’t have snotty children so my clothes don’t get very grubby.
