I've struggled for anxiety about a year, I managed to cope with it for a few months now and got my life finally back together. However from last week things screwed up. Suddenly i started feeling really uneasy, and got these weird sensations in my chest , i really don't know how to explain it because i've never got it previously when i had panic attacks. My heart also started beating in a weird way. Next day i got fever, and i assumed these symptoms were caused because of it. However, now that i'm healthy, i still started getting these symptoms. Other than the heart beat and the chest feeling, i started feeling really scared , paranoid and this ugly feeling that im going mad. I've tried distracting myself, i tried thinking differently but nothing helps. Im not sure if its a panic attack either i honestly don't even know what could cause it. I completely lost sleep because of it. I go to therapy but i don't know how to word it so i can tell my therapist. I'm scared im going to go crazy. Any advice? And also does this count as a panic attack? The weird thing is it lasts a lot, for hours even. It tones down and comes back again?
