Do I have night anxiety?

I saw something on the tv about night anxiety, then I searched it up and the symptoms looked similar. I had to have the light on older than a normal child. I always go to bed thinking someone is going to break in so I have to lie facing the door. If I hear a noise I think it's someone breaking in. I lie awake for hours trying to get comfortable. And I lie on my phone for hours. Thank you ladies X
