Hi, been reading this sub a bit after leaning recently the pounding in my chest is something called a panic attack!

Back in early December I was going through a stressful period changing jobs and fainted unexpectedly, everything seemed to be ok but I started to worry about what the meaning of it was as it hadn't happened before. Next day I get an eye strain making my worry worse then the day after that I had reduced sensation in some parts of my face (same area both sides) which triggered a full on panic attack. Tests showed my blood and circulation to be fine so I put it out of my mind but I kept thinking about the fainting and face numbness and googled it, big mistake. Was on edge but sleeping ok over Christmas but had developed a sinus infection and my eyes were constantly tired, then in mid Jan I developed tinnitus in my left ear, common for sinus problems. but I noticed that when I got panicked it would get so much louder. Sinus infection mostly cleared up with antibiotics but the tinnitus is still with me, albeit much reduced. The face numbness comes and goes quite quickly so I don't panic from it now but still worried. Anew thing started on Friday where my eyes became very dry and burning that had me in a bit of a panic again, been treating it with eye drops and warm compress which is helping but I also notice what felt like temporary reduced sensation in my eyes. it clears up quickly but scared the life out of me.
Never had anything like this before December last year so don't know if I'm just stressed out or genuinely sick, any advice is appreciated!
