I highly doubt bicarbonate of soda will work on an already dry stain that’s been hidden, dabbed at then hidden again.
Why have you chosen this method? Beyond all the other methods that have a chance of actually working? Is it because you don’t have to actually wet it or scrub it with stain removers? If so, I’m afraid sprinkling and hoovering will do absolutely nothing against an already dried in stain.
It just won’t, and you’re winding yourself up and up into a fever of failure and panic by making choices that won’t work.
I think you are too scared to even clean the sofa properly, which is not a normal state to be in. I don’t know where you’ve got the idea that wetting the surface will somehow cause longer term mould inside the cushion. It’s highly unlikely, and I mean so highly unlikely that it shouldn’t be part of your decision making right now, unless you’re pouring a bucket of water into it!
It’s concerning that you are making this extremely unlikely slight possibility a major influence in your behaviour right now, when you have actual real worries to focus on.
It kind of feels like you are terrified of the reaction of your husband, and yet you are not making good decisions to put yourself first in this.
You don’t want to leave yet and you want to concentrate on the sofa? Ok, then actually concentrate on it, don’t make half panicked attempts that clearly won’t work... its like you’ve decided you’ll fail already?
I think you might be very anxious and worried to the point where you can’t prioritise or work out what to do.
And if so, that’s your brain showing it’s struggling to function under the constant fear or stress. It’s what happens to even the cleverest, most amazing brains in the world, when that person is living under constant stress and fear. It eats away at you, until you can hardly function anymore. And it traps you because you get afraid that you can’t function on your own (which by the way luckily isn’t true, as you get your abilities back as the fear wears off).
And you can tell me to buzz off of course, but I’m worried that this is happening to you too...
Even when you’re telling us the story of the stain on here, you say it’s your fault... but when you explain what happened, it’s clearly not your fault - it’s actually the fault of your daughter.
I’m not sure what’s happening here, it could be that you are protecting your children from your husband, but I’m worried it isn’t actually. I’m worried that it’s actually that you get given the blame for everything that happens? And you’re started to believe that it’s your fault even when it clearly isn’t?
