I'm going to be 30 and last year I had some anxiety when I noticed a hair that might be grey(my hair color makes it hard to tell because it's light brown mixed with dark blond that is in different shades).
In my case, the anxiety isn't about aging itself or the grey hair itself, but it has to do with how I know society perceives women and aging.

I'm a gender non-conforming woman who is very masculine presenting and I would never be comfortable with things like make up or hair dye. It's already been seemingly impossible to be found attractive by any man so far so I worry that turning 30 will make me even more undesirable and that once I start getting grey hairs, that too will add exponentially to it. I know it shouldn't but ...
