I never knew for sure if there were cameras in my room, but ambiguity was always part of the abuse. There were at least a few places they could have hidden one, and I was always nervous around those places (small hole in the ceiling for example). My dad was some kind of weird thing back then, like an undercover cop that's not actually employed by the police. A narc, maybe? Or just a "friend of the police"? Anyways, he was really sneaky, really suspicious of everything, had a power/superiority complex, and was a master of manipulating people into self-incrimination. Everything was always a trap, nothing could be trusted.

There was a constant looming threat of someone just barging into whatever room I was in to "make sure I wasn't doing drugs". They were always accusing me of nonsensical things, mostly of being a bad person and a drug user and a liar, none of which I became until later in life. One time I had to sneeze but it went away, and they accused me of making disrespectful faces at them and took away every source of happiness I could possibly find for a month.

That was the punishment every time, plus usually a whipping with a leather belt, and if I cried or moved it started over. They'd take away every possible avenue I could use to gain any positive emotions, and these punishments were in standardized increments of one month. Any mistake during that period effectively doubled the length of the punishment, though I'll be honest I never kept good track of the time, and I think they purposefully messed with time as an extra layer of abuse.

In fact time was one of the things that got me punished the most. I'm autistic and have ADHD (among other things), and they simply would not accommodate my time blindness, attributing it to a character flaw. I asked for help remembering to take the trash out on time; to help they took away all my shit for a month and said if I wanted it back I'd stop being so lazy and defiant. I spent whole years like this.

They read my text messages and listened to my calls. They didn't tell me this, they'd just come out and say "I know X". It was never anything actually bad, just stuff they didn't like. There was this weirdness around the phone, like they really wanted me to have it. When I started using encrypted messaging apps, they demanded the password to my phone and started making me leave it in their room every night. They claimed it was "because I just sit up all night on my phone", even though that was a total lie. They made me feel like a liar for telling the truth.

Their abuse was primarily focused around their openly admitted desire to use me as a tool to improve their social status. I'm not exaggerating, they said those words to me. I was a "bad person" because being myself hurt their public image.

All of these things were said to me during hours-long brainwashing sessions. He'd sit beside me, 90 degrees to the left, and he'd punish me if I didn't look directly at him. I'm pretty sure this was the primary cause of my chronic neck pain. He'd explain to me in great detail just what kind of piece of shit I am for being who I am, down to every individual detail about myself.

I have to mention the moment I started standing up for myself. During one of these hours-long one-way roast sessions, I said something (don't remember what) that upset him. He threw an entire glass of milk in my face and then told me to clean it up. I said "you made the mess, you clean it up LAZY". So then he tried to make my step-mom clean it up, and I said the same thing again; she didn't do it, she doesn't deserve to clean it up. Unfortunately she was broken by then and cleaned it up anyways. That's about when I stopped listening entirely and became disillusioned with the idea of authority.

To finally answer your question, I am only ever naked in the shower with the curtain closed, or under my covers in bed. Even then I feel really weird about it, it still feels like people are watching, but I can't keep the same clothes on forever so they're just gonna have to look at it.
