I am not sure if this is related to depersonalization but sometimes, all of a sudden, I get this feeling/obsessive thought that there's something wrong about my appearance, something like a delusion but it's not visible, it's only in my mind and that picture of myself stays stuck with me. I look normal in the mirror, but still, my mind doesn't let me feel normal about myself and that thought takes over me and I am focused on it all the time untill it goes away. So, my question is does anyone happen to know what this might be.. is it only dp or maybe ocd or something worse?
