Body Image Issues

Been feeling like absolute crap about my looks lately, due to repeatedly being mistaken for being not only elderly, but a man or a transgender as well (I'm none of these things: I'm only 49, and am and always have been 100% female). I don't know what people are seeing that make them think these things: I mean, where's the grey or white hair or wrinkles? And big does not equal man. There is such a thing as plus-sized women, and we don't all look like the gals in the plus-size lingerie catalogues (first of all, those gals are in their 20's, and are strapped into shapewear. Some have even had plastic surgery. I, on the other hand, am in my 40's, don't wear shapewear and can't afford plastic surgery).
