So I have some very mild anxiety (a symptom of a different mental disorder) and I've had a few panic attacks before and during stressful times I have over anxious thoughts which come with the usual physical symptoms (tight chest, fast breathing, a little sweaty, etc). Recently though I've been only getting the physical symptoms without any anxious thoughts to go with them. Usually I think something like "I hope I'll have enough money this month since my hours got cut", cue the physical stuff and more anxious thoughts. But recently, I all of a sudden get all the physical stuff without any anxious thoughts. Just all of a sudden I have trouble breathing and swallowing and and my heart beats fast and my chest feels tight and a I have knot in my stomach. And it's not like I have nothing to be anxious about, I mean don't we always? But no thought ever triggers it. Can someone help explain this? Should I be worried, or, haha anxious?
