If mental health matters, then the mental healthcare system needs to practice what they preach instead of just say things to look good for their psas. There’s so many homeless people in my town and I easily see myself becoming one at this rate. Do what you can to take care of yourself. Try to avoid shitty drs and therapists. It’s not always easy.
You need to be drinking water. That’s the scariest part of this for me. I realise this probably plays into the delusions, so if it helps you can look at my comment history. I’ve made reference to it a few times already: I live in New Zealand, and I’ve never even been to the states. Please figure the water thing out. Being dehydrated will not be making anything easier, and it’s the simplest problem to solve. Would you feel better drinking filtered water?
If tap water freaks OP out, they could maybe try one of those basic water filter pitchers. Pour water in, it runs through charcoal which pulls out anything bad, clean water comes out.
For extra peace of mind, OP can consider getting a TDS (“Total Dissolved Solids”) meter. My boyfriend got one and uses it to figure out when we need to change water filters.
I normally wouldn’t recommend fiddling about with your own water filtering solutions, because given clean water they’ll only be making it dirty. But if your worry is literal poison in the water supply, carbon filters will pull that shit out. It won’t fix the paranoid delusions though.
Dehydration has been shown to exacerbate the symptoms of mental illness, so it certainly won’t make them worse!
