My body is deteriorating fast as a result of autoimmune disease/thyroid disease/PCOS/VSS, all that began after a certain medical procedure. I'll keep it short: I had resistant high blood pressure after this medical procedure as well. I had to quadruple my medication and add on a second pill, at which point I started feeling like I was swaying on a boat at all times. It got progressively worse over a course of a month, and I thought it was possibly vertigo so I had tons of balance/dizziness tests done - all of which were negative. My doctor suggested getting off the medication(s) and sure enough that resolved it. But that was a very traumatic period (within the already traumatic period of all these issues going on) because I couldn't walk, couldn't sit still without getting nauseous - it felt like I was going backwards on the zipper carnival ride.

The swaying sensation has returned. It feels like I just got off a boat and sometimes feels like I need to grab onto my desk or something. Even when I'm laying down it feels like I'm on a raft in the ocean, and if I'm laying on my side it sometimes feels like I'm going to fall over. [Read more about the chronology of events here](https://www.reddit.com/r/AskDocs/comments/vl0xoh/swaying_sensation_when_sittinglaying_down/). **Tldr:** 3 nights ago didn't sleep at all, had to go on a plane where I got multiple tests done - MRI with contrast (non-iodine), evoked potential, EEG, minor bloodwork, slept well that night with no issues of swaying. *Also, last time I was at hospital I started hearing my tinnitus/hyperacusis again, so of course my OCD was fixated on hearing tinnitus once I got there, and of course I now hear it due to the hyperfocus lol.* Next day had 3 doctors' appointments, got on a plane, got home late and started feeling that swaying sensation when I got into my bed. Yesterday didn't feel it most of the day, started getting worse at night as I was sitting still, had it when I got into bed, slept 7 hours and woke up naturally. Then this morning didn't have it at first, but within 2 hours it started again. My tinnitus/hyperacusis has gotten a little better, it's still there, but not the center of my hyperfocus right now, though always when I'm anxious about anything I am listening out for it; that I know is my hyperfocus playing tricks on me.

I've been on the same medication (which as worked wonders for my blood pressure) since November and it is a relatively low-medium dose. No other change in meds or lifestyle besides the aforementioned.

I've developed severe medical anxiety/OCD due to all these issues, and as a result I do personalize sometimes. I am under a lot of stress with professional exams, but again - I have been under this stress and anxiety for weeks before this. My biggest fear is losing control of my health, and given the PCOS/thyroid disease were just diagnosed while I was away on this hospital trip a few days, ago, that definitely felt like I was losing control. I don't feel depersonalized per say, I just feel like "omg another new symptom that I thought was gone is coming back omg things are getting worse". 

Does this swaying sensation sound like anxiety/hyperfocus? Or does this sound like something more serious? Thanks. :(
