I feel your pain... once I wrote down in my journal about how I would love for nothing more than to be able to go out into society with a mask of some kind on. Actually, when I originally wrote it, I said 'a paper bag,' but I was just assuming the worst case scenario. I don't want people to have something to link the embarrassment that is my physical body to. It just feels humiliating that I have to subject myself to people actually having the chance to look at my face.
Even I don't look at my face for that precise reason. I don't want to associate it to 'me' and I don't want to be reminded that its attached to me. Therefore, my life would be a lot better if I just didn't have to show everyone it, either. I've mentioned it on here before, but I unironically force myself to believe that my face is obscured by shadows, with only my left eye piercing through the dark, and I tend to imagine that as my real face. It makes me more comfortable.
Unfortunately, no such thing exists in real life...
