Does being attractive determine how we're treated?

I'm at the gym today. I go to Zumba as usual. The instructor rarely comes anywhere near me. He rarely ever says hello. I usually give a smile as a greeting, and though my teeth are spaced and crooked, I do my best to show a friendly side. But still nothing. I hate wearing make up because out here people react to me with stares and snickers and I'm always confused by this because I assume I look halfway decent, but people's reaction would make me think otherwise. The son of a bitch I'm married to either comes home late every week night, and parties with his friends on the weekend while I'm stuck with the kids for 16 hours. Can you imagine trying to keep 2 young kids busy for 16 hours without TV? How much can they play? Color?, nap? It's maddening. But I'm often grateful not to have to face the cruel world that laughs at me, or whispers behind their hands, or pretend not to giggle when I walk in the room. How ugly am I? It's weird. I think I am far prettier than the way the world sees me. I overcompensate with the kindness and humility, only to be treated worse. My kids are no help, I try to avoid attention, but my kids make a scene almost everywhere we go. It's become second nature. So, I've decided to stop going places with them. They've simply become a nuisance, crying, throwing tantrums, misbehaving, throwing things in stores, breaking things, knocking stuff over, falling down, , or injuring themselves. I am just tired of it. I love them dearly, but damn it I need a damn break. I work out to relieve stress and they go to the children's play room at the gym, and rather than run around and release their energy as their supposed to, they actually sit, color, watch TV. This confuses the hell out me because they run a damn muck once we go anywhere else. The point is I'm tired of being treated badly. I can't be quasi moto. So why the fuck am I treated so damn bad?
