Can’t sleep

It’s so dumb. I struggle to sleep because I’m always afraid someone is going to come in my room and stare at me. Like sexually while I sleep. And I know it’s cause I was touched as a kid in my sleep. But you can’t snap out of it. I’m never comfortable and I can’t lock my door or I know it’ll be a big fight. And it’s not worth it. I just wish o could sleep right now.
