Philosophical thoughts due to fear

I have always had very strange thoughts about many things. I used to think I was the anti christ, I was being sucked into another dimension. Now I feel so weird after thinking how when you strip everything from human beings all our conciousnesses resemble. From the strongest man, girl and everything we are just an unthinking thing. Our faces, bodies and gender are all additions. I feel so useless because of that. I'm terrified. I look at everyone. She's cute but she's just like him, or that animal. I imagine that deep unedited version of us all is like a tiny dark pea. Its all the same so who we are is not really us. I'm not proud of anything any more. Its all additions talent, good looks, desire. I hate thinking like this. How do I stop?

..reminded me a bit of this https://youtu.be/1IUX0Qy-IDM?t=337 (watch the whole thing, and trilogy, if you have time)

How do you stop? No idea.
I'd try leading those thoughts in certain directions and putting them at creative/philosophical work. Sometimes I'm more surprised by people who don't have them.
