Usually happens when I am alone. There's a sudden movement or shadow in my peripheral and it just surprises me and usually results in a panic attack.

I've been jumpy these days, the door of my room makes a bit of a noise, and that is enough to make me jump and get a mini heart attack.

 I couldn't even go back to my room once, i was so scared for no reason :/ even though it makes no sense, i thought my room was going to kill me.

There's a hole above our bathroom and I thought I heard someone breathe, I feel like I am going crazy.

Whenever I brush my teeth i have to look left, right and behind my back every few seconds just to feel safe because I feel like I am going to get murdered, 
It makes no sense and I know that but holy shit my body acts on instinct and jumps like a surprised kitten.
