I have ptsd and have an issue when men I don't know are in my space. When I get to know guys and I determine they're safe, then I don't mind as much, as long as they don't touch me without my permission. Today, I found myself in an all too common situation. I was waiting in line to check in for an appointment. A man came in and stood behind me and I felt like he was way too close for my comfort. I kept moving forward, but he just stepped forward more. I noticed that I could not move up any further, so I stepped sideways. I think the lady in front of me was irritated with me also. I didn't know what else to do, and even then, I felt like he kept getting closer. I felt really panicked. I wanted to run away. Does anyone else struggle with things like this? I try to remind myself that I'm safe, but it's like my body and mind are on completely different levels. They feel disconnected. What can I do in the future when my space gets violated by strangers? Is it ok to tell them to back up?
