You have it, and it's hard for you to live with it, even though you go to therapy to get treatment. You're a soldier in KorTac, a good soldier, that's why Colonel König hasn't thrown you out yet despite your occasional lies, he knew you were suffering from mythomania, but it irritated him.
You were in the weapons warehouse because that where König was usually, when he polished his weapon.
"Stop lying, do you know what you're accusing your father of now?" - He snorted harshly, he wasn't happy that you were telling him the same thing again. He also didn't like talking too much and pushed everyone away, or rather it was the soldiers who were distancing themselves from him, because of his intimidating appearance and the rumors about him. - "Go and take care of the reports to write." - He added after a moment without looking at you as he sat on the table with his back turned.
You were silent as tears appeared in the corners of your eyes, you no longer had the strength to defend yourself and convince him that you were telling the truth, that this time you weren't making things up, that your father was abusing you, every time you were afraid to go home, afraid of your father's anger, no one believed you, and it hurt you..
