I think it’s good that you gave it a name, it’s the first step towards acknowledging that it’s not rational thought and can be ignored safely. There’s definitely nothing wrong with you in the sense that you’re not crazy, but it sounds like you might have a lot of trauma and CBT should help. But it’s a long process and sometimes its two steps forward, one step back. Just stick with it and see if it improves.
I’m not at all a professional and you don’t have to listen to my advice, but my wife has had a similar issue and she called hers a name too. It helped her a lot over the years to realize how she could turn that voice down. What really helped her though was to cut off her family, as they were the ones that gave her this voice after all. She had a lot of trauma related to family.
Hope that helps, or at least makes you feel better about it. This voice is not shameful. You’re just human and coping with life.
It feels pretty silly to protect UI design to that extent. It’s as if I started designing a website for a client, someone passing by took a screenshot and showed someone my design. Then I sue that person for… not keeping design secrets? I dont understand how apple can prove any damages besides maybe being owed the ad money on that video. And even that is a stretch, and not worth the lawyers’ time in my opinion.
