Reasons I'm Convinced I'm Dying

Or maybe it's just one of those periods where I feel like my uterus will kill me
  1. Every time I stood up today I got tunnel vision
  2. My lower back has been in pain since I woke up
  3. My hands have been shaking more than usual
  4. Also my legs
  5. My heart has been beating faster than usual
  6. Stomach hurts if I blink wrong
  7. Lightheaded when I stand for too long
  8. Laying down is the only time I feel comfortable
  9. What have I done to hurt you, body?
  10. Update: this may just be anxiety and period symptoms cavorting with each other
    What fun!
