Witnessing something you shouldn’t have seen

I have to talk about something that happened to me yesterday with people who can understand why it’s been traumatising to me. TW sexual content Yesterday I was at home, I was heading to the kitchen because I needed gloves. My father was in there like he usually is. I smelled something sweet, so I assumed he was baking, and I walked in. He was sitting at his usual seat at the table, and when I walked in he jerked, in a way that was immediately suspicious to me. But then he took down his phone, and I saw that he was watching… well, let’s just say something dirty. I don’t know if I’m overreacting, but it was a little bit traumatising to me for many reasons. First one, obviously, it would shock anyone to see their parent do something intimate, and I know it’s not fair but right now I can’t see him like I did before, and not because it’s wrong because it isn’t, it’s just that it’s something you do not expect a parent to do, even so if they are over 60 and pretty religious. Second one, it’s the fact he was doing it in the kitchen, a shared space, where I eat. My house has always been my safe place, a place where my compulsions related to contamination calmed just a little bit down, and now it’s not anymore. And I don’t have any place to go, and I have to continue sitting at that table in the kitchen without trouble because then my mom would ask me why I don’t wanna eat in the kitchen anymore and it’s really not my place to tell her what I saw. I don’t know what to do. It’s already a difficult moment for me, I’m depressed and trying my best to do the things I have to do everyday, one thing that made me feel better was the comfort of my house and I don’t have that anymore
