Just wanted to leave

I would want to start by saying I’m so done. I want this to be over. Financially we couldn’t afford for baby’s daycare, so my husband brought his parents. They both are hell to live with. My house is poorly clean and my kitchen is disgusting to stand. I kept my baby’s bottle in my room. I stopped eating. I eat only lunch and that too sometimes outside. I found hair in all over kitchen, sink , even fridge. It pisses me off because I kept my house even after three weeks pp with no help. I want my baby to healthy. They both were shaking my baby or spank my baby on his butt just for fun. I couldn’t tolerate. I go to school and I’m applying grad schools. I showed my anger to my husband. He said he was talking but I don’t seen him getting angrier with them. But he would be angry if I tell him what do they do . I’m in the verge of frustration. That bitch was telling my 5 months old, describes me as a trash to my baby and says my baby is a mini devil. I couldn’t take today. I’m in so much anger and frustration. We spent all our money to bring them here. They have been eating three times a day and sleeps rests very well wheras me struggling. I’m still breastfeeding my baby though i produce low. I just want to leave my husband. Because of him, we had to have connection with that bitchy people here. I don’t want to listen my baby is their grandkid blah blah. I don’t care. She also tells my baby you’re from our family not your moms family. She never teaches mom, she says dad, grandpa blah blah. I just want this to stop.
