I have lots of problems when I try sleeping by myself, I can't even sleep by myself.?

Alright here is the situation, I am 11 years old and can't sleep by myself.
I tried yesterday but I always get freaked out.
This is what happens.
My heart starts beating really fast, I hear my own breath while breathing I get freaky images Like REALLY scary in my mind and I keep thinking about scary things.
I try thinking about other things but I see the image right over it.
HELP I WANT TO SLEEP BY MYSELF!!!
I already have a night light in my room but i can't really see it.
to NINJA???
My mom and dad won't let me have a pet
I don't know why.
I don't have a T.V in my room either
I do not have the cable plug in for Cable..
When I can't sleep by myself I just set up a small bed on the floor in my sisters room
I just take some blankets and my pillow.

Whoa Boy! Calm down!
Dont worry, its just a passing thing, You'll be fine in no time, just lie down and concentrate on your breathing. Count backwards from thousand. Think about the day ahead. Drink a glass of hot milk before to get ready for bed. Take a nice warm bath before you sleep. It'll be fine before you know it.
If it still doesnt help, try and use this program:
