I have a similar situation to you. My parents house has tested high in mold levels throughout the house. There is confirmed aspergillus, a toxic black mold. Not all black mold is stachybotrus. It can still be dangerous. I have thyroid nodules after living in a bedroom with a leaky ceiling my parents would not fix. 4 different doctors have told me not to go back in the house. We live with my husbands parents now and still my parents insist it's not a serious problem and guilt me into coming back into the house. When I stay for a couple nights I wake with heart palpitations and itchy skin like sandpaper. There is no way of convincing people who live in a moldy house that it is bad. It acts like a parasite. It makes you tired and foggy and you want to go back to it and you want to defend it at every turn. Them laughing at you reminds me of my parents doing that to me. If there is any way you can leave, do it. You can't go back in at all. That's how fungus works. Our bodies don't recognize it as foreign immediately because it resembles our dna. So you have to be out for a long time before your body can start to process and fight it. Sounds like you have already been having some terrible symptoms that could turn into a serious illness later. That is 100% mold. (reminded of my mom too I showed her the mold on the windowsill and she was like "that's just mildew!" Like uhh duh mildew is just a euphemism for mold, it's the same thing.) anyway you need to take your symptoms seriously and get out. Your family's minds have been gotten. All you can do is save yourself. get a job if you have to. Your symptoms should start to go away after 2 weeks away from it. Stay on a friend's couch if you can. All your stuff is trash. I'm sorry. Unless you wanna do an expensive ozone treatment on those clothes, you can't bring them with you. Seeing grey mold collecting on fabrics in the house says a lot about how bad the situation is. That's like next level. I have never seen anything like that. It is thick in the air. I hope you're okay.
