Any ideas?

this has to do with health anxiety apparently. I’ve had big issues standing and walking period without feeling weak and like the floor was moving or ima fall over New fear of eating some things because of my stomach going nuts and this congestion and throat feeling, and avoiding some meds. But wow. I apparently have a hyperthyroid that after all this dismissal was found medically. I don’t even know where to start but I’ve been in forums for a bit but never knew it’d be this bad. I’ve had gerd (diagnosed by a few but not a G.I), no idea how. But it seems I found out I have LPR (that’s me saying it) my nose is always blocked, turbinates big, tonsils are big, throat feels tight and weird and such. Allergy test was clear, I also have a lot of burping fits and trapped gas and lots in my chest and throat, maybe I swallow air, I pop my jaw like crazy, I hear tmj goes with gerd (makes 0 sense). Been prescribed zofran, famotidine, omaprazole, Flonase, Azelastine. Just not sure where to start to beat all of this. I’ve thought it was my heart or blood pressure or whatever else. Had tons of tests ran so far with more on the way. (Not stomach ironically and that’s probably whole thing.) just don’t know. Got visual snow and this vertigo shit, fog and fatigue and just so much shit in the last year and I’ve done so much (except try the stomach/nose meds - just thyroid)
