I always imagine scenarios in my mind that hurt my feelings normally there based off my own experiences like I was bullied at school now I've change schools and I'm no longer bullied but I still full expect people to bully me and make up a scenario we're people are bullying me that upsets me. This normally happens whenever  I'm feeling even just mildly anxious then I make myself worse by making up a scenario in my mind that's completely unrelated. For example when I feel like people are ignoring me I'm upset then I make myself more upset by making up a scenario like my cats gone missing or someones hurting me.
