I've needed to vent for so long

Okay so maybe it makes me a bad person to be bothered by all of this but I am and these are my feelings. My mother in law lives with me and she's effing disgusting. When she walks by, she stinks and I'm pregnant so sometimes it literally makes me puke. She showers once every 2 months. She smokes over 2 packs a day and never brushes her teeth. She drinks coffee left out for 2 days in her room. She wonders why all of her teeth are rotten but smokes and drinks coffee in the middle of the night without brushing. She says she showers every 2 months but I don't believe even that. I've only ever heard her in the shower once in the year I've had her in my home. I'm absolutely repulsed by her and I don't want her touching my kid. She has had some sort of vaginal infection for like 6 months that she complains about but won't get taken care of and it makes the bathroom smell absolutely horrid. Ti the point where I'll drive to go pee somewhere else rather than smell that. She has diabetes and is over 300 pounds and just doesn't take care of herself. She orders pizzas nightly almost and never checks her blood sugar. I just have never been so repulsed by another human being in my life.
