Rant sorry

My sister and I got into a fight. Long story short it was over something that got taken way out of hand. My husband and I fight and sometimes he’s a jerk. But we’ve been working through our issues, and after the baby and stress that doesn’t help. However I got into a fight with my sister, and she says how our child is gunna be miserable and that choose my husband over my child. She starts just going off on anything she can use to offend me. My husband works 50+ hours a week so I can understand that he’s tired. But I am also tired somedays because my child is quite the handful ( I’m not complaining but I’m only human, sometimes I get stressed and overwhelmed ) she then tells me, maybe you shouldn’t of become a parent if you’re gunna complain. Mind you she is also a mother.. the difference she doesn’t let her S.O work because she feels “ he should be at home with his family helping out. “ and even when she “lets” him work for 2 hours she just goes to a family members house and they take over.. my point is she gets help, I do not! I’m here doing it alone most of the day 5 days a week. We used to see her all the time, but my whole house got covid and so did hers, after that my parents who we lived with helping my sick father have said they don’t want us going to others households and nobody coming over, I do leave to go grocery shopping from time to time but that’s it. She then called me lazy and a bad mom for keeping my kid inside all day... and that saying oh I’m just trying to be safe because of a national pandemic sorry is an excuse. Mind you I haven’t sworn or said anything bad towards her and I probably could but what’s the point? Sorry if this was long. It was quite the rant
