Fear of getting shot.

I've been getting extreme paranoid thoughts, especially at night, about someone breaking into the house I am at (whether it be my friends, parents or my own home) and shooting me. I can barely sleep at this point until the sun comes up and i feel somewhat safe again. Two nights ago i literally was hyperventilating. The bed at my parents house is right under the window and im convinced someone's going to shoot right through it with a gun.

All i can think about is a bullet flying through my head. Im so fucking exhausted and scared.
