I feel this sense of panic and am getting tremors while handling things like my hands are shaking and all. I feel this poking pain in the middle of my chest and a tight feeling overall, but it also feels like there is trapped air, I haven't eaten properly in the last 24 hrs but have taken a lot of fluids not alcohol. The problem also is am panicking but my heart rate is at 67-72 what should I do, my stomach is also bloated. I feel like passing stool but am constipated like hell.
