Yeah I'm like this and it's not really a trauma thing for me. I'm just autistic and ADHD which basically means I take advice too seriously and I have a bad habit of getting into someone's field of view or in their way by accident. As a result of being advised to be less visible every time I got in someone's view, I accidentally became invisible. It's something I've been working on lately actually and I've noticed I scare people less often since I started thinking about it
