How long does it take get out of Hyperstimulation

So I have been to several doctors like neurologist, cardiologist, rheumatologist. Done a lot of tests and MRIs. Everybody is telling me that my symptoms are from stress/anxiety. My first symptoms a few months ago were twitches in the left leg only. A month after that I had my first panic attack (however I didn't know at the time that it was a panick attack...u know first time happening). I got nausea, dizzyness, cold feet, cold hands, the "I dont know what is happening to me but I'm probably super ill and going to die" feeling, some heart palpitations, more twitches etc. Since then with those symptoms I kept being anxious about my health like 24/7. I went the MS/ALS/PArkinson rabbit hole... and probably keep fueling the anxiousness/stress.Now my symptoms are some twitches that are in random places, my arm (deltoid) is shaky but only when I lower it, same thing with my neck when I lower or upper it, "shaky" legs feeling kinda. I have also some pain in the muscles especially the deltoid that is shaky, a bit of pain in the ribs, pain in my hand joint, feeling of a weak muscles a bit. I started to read about anxiety on the website anxietycentre.com that all could be related to yeah...anxiety. I also read about Hyperstimulation, which could explain a lot of things happening to me. So to the people that have hyperstimulation...how long does it take to recover from it to stop having symtpoms when you are not being anxious anymore?
