I'm really sorry to hear that. Mold really shouldn't exist. I have had mold problems too, they suck big time.
Why won't your parents take you somewhere with no mold? Or get rid of the mold? I think it might even be illegal to live at a house which is unfit for living.
I hope you can find a way out. It's awful that even when you live like shit, you're still likely to live till at least 40-60. A death should be quick and without suffering. Life should be without suffering too.
I read that you can die of eating too much natrium sodium (salt is about 45% of natrium sodium if I recall correctly). I tried it myself, but I couldn't take the taste of salt. But there are people who have died after eating salt. One woman drank a whole bottle of soy sauce, went to bed, and was found dead the next morning. The amount is something like 100-200 grams of natrium (not salt, but natrium sodium which is used in salt). I read a really good study about it but can't find it anywhere anymore. It listed people who had died of sodium, their age, how much they had ingested, and how quickly they died.
Of course you have to be very careful with salt. It can be unpleasant, take a long time, and you have to take a lot to make sure you don't end up somewhere between death and life.
Oh, and one more thing. Make sure it isn't food allergy. Because I developed a peanut allergy out of nowhere last year and almost died a few times.
But I really hope you could get out of the house or get it repaired, and please, try not eating peanuts in case it is related to them somehow. It might not, but hey, you've got nothing lose by trying it.
I hope you'll find a solution yourself. Remember to keep windows open to let the rooms get fresh air.
...You could of course buy an ozone maker, an ozonizer. I bought one and it has helped. It can get rid of mold and bad smells, but you can't be in the same room while ozone is there because ozone isn't good for humans and animals. You put it on, use the timer, get out of the ozone's way, let ozone do its thing, and then air the whole place completely. And the area must be sealed completely, so that the ozone can't escape through door gaps or keyholes. Ozone dissolves quickly, if I recall correctly it was something like "one hour of ozone takes two hours to dissolve" so in total three hours of waiting time.
But yeah. I hope there'll be better days ahead of you!
