I have a celebrity doppelgänger and it has been freaking me out to the point of panic attacks

This sounds really weird because I’m sure most peopled would just shrug it off as “oh that’s strange” but I literally can’t stop thinking about it. It’s almost making me feel like I’m being impersonated? It freaks me out to look at pictures of him it feels like someone is doing things in my own body without my consent.

For some more context, it’s not just a “Oh cool we look similar!” I am not exaggerating when I say we look EXACTLY the same. He even has the same exact HAIR STYLE coincidentally. The only difference I can point out is that I have red hair and he’s blonde but he’s almost sort of a strawberry blonde too. And about the panic attacks, whenever I see a photo of him I literally start to get the sensation that I’m having a nightmare and I’ll start hyperventilating. I can’t even watch the stupid show he’s in anymore because I’ll start panicking. When I first noticed I didn’t care NEARLY as much but now it’s descended into THIS and now it’s all I can think about. I really need help because I can’t live like this forever. Any advice would be appreciated, thank you.
