Drink some prune juice---that will help you go poo. The dizziness is happening because you are NERVOUS. My suggestion to you would be to start a hobby so that when you are alone you can distract your mind and do something productive. Write in a journal, paint, draw----buy a sketchbook and EXPRESS yourself. That has always helped me when I felt nervous, bored, or angry.
THHANK YOU FOR ANSWERING ME IT FEELS GOOD TO KNOW SOMEONE IS HERE. I'LL TRY TO DO SOMETHING TO OCCUPY MYSELF BUT ITS JUST REALLY HARD FOR ME BECAUSE I CAN'T GET MY MIND OF ME BEING ALONE AND SOMETHING HAPPENING TO ME BECAUSE OF ME NOT POOPING. AGAIN THANK YOU
