Yes, it does, thankfully
i've been where you are. It is the worst, no? I would rather have a constant pain in my arm or stomach, even a migraine, than have something mess with my mind...as in making me fear what isn't fearful, or making me worry over something that should not be a problem. And I get the sleep thing. Without it, I am not me. All my symptoms worsen. When I get it, my day goes well. But I still worry about it, because it is hard to make my body go to sleep when it should in order to get the rest I need to complete the next day.
No doctor helped me for 20 years, till I was introduced to a doctor that considers natural healing before prescriiption healing. I always believed my system was poisoned in some way. And after consulting with my doctor and trying different methods that deal with viral/bacterial problems, and mercury toxicity, I have improved about 50 %, most of that in the last five months when I started to add iodine. If you want, you can check my past posts, under the names anvil and blues and it will show you some of my journey.
Best wishes
