I've had allergies as far back as I can remember and this year has been the worst I have experienced in roughly 20 years. Incredibly, infuriatingly itchy eyes that are puffy and swell nearly closed, intense sinus pressure, ears popping, intermittent sneeze attacks with a constant fully stuffed nose for multiple weeks that never stops dripping, snoring all night long, and the occasional hacking because it feels like everything is running into your lungs. I know how debilitating allergies can be, it is awful. Thankfully the worst of it ended about 10 days ago for me after about 3 weeks of pure misery.
What you describe sounds nothing like seasonal allergies. I don't know you personally or know of your potential anxiety issues but I don't think that that is what you are experiencing either.
I would quickly get myself off trail and to a doc.
Like yesterday.
