Crazy ass in laws

So a little back story I’m 14 weeks pregnant struggling to sleep and I work overnights so I try to sleep during the day. Friday around 6 I get woken up to my fiancé’s nieces screaming and my in laws dogs fighting, so I jump out of bed and go running out there to see what’s going on and break it up, by the time I get out there my father in law has already broken it up so I asked what happened and apparently one of the little girls was teasing the dogs with food and then threw it in the middle of the dogs which started the fight which I mean there dogs and it’s food so it happens, so I go to lay back down and start dozing off again 15 minutes later I hear the girls screaming again and something break, so I go running out there again and I’m like what the fuck is going on now, the 11 year old tells me that my father in law dragged one of the dogs out by the ear with a gun to its head because he thought that dog is the one that started it, and now I’m pissed because this is ridiculous these kids are 6 and 11 and he pulled a gun out in front of them the 6 year old is on the ground screaming none stop shaking and covering her ears, so I go outside and my mother in law got the gun away from him, and they casually ask me why I’m up like nothing even happened and I fucking lost it I’m sticking up for these kids and I tell him, I’m sick of being woke up when I’m trying to sleep it’s not like on my days off that I wake everyone in the house up at 5 am I can but I don’t, and then I go on to say you know you are being absolutely ridiculous the dogs fought over food from being teased it happens they are animals but you didn’t have to pull a gun out and especially around the kids, I said if they were my kids they would never see them again because that is absolutely terrifying to a kid, which pissed him off because I guess he thought he was in the right and he said he doesn’t give a shit about my baby anyway, and ever since I got pregnant I’ve been lazy and don’t do shit anymore, but since about 4 weeks I have had morning sickness so bad that I projectile vomit at least 5 times a day and if I’m not puking I have bad heartburn, before I got pregnant I used to do all the cooking cleaning and everything around the house but ever since I haven’t been able to no one has picked up the slack, I had just cleaned the house 2 days prior to this fight too now neither one of my in laws is talking to me and they are talking about moving out of the house we have a lease on together that they know I won’t be able to afford with just me and my fiancé so I said that’s messed up because I would be homeless and I’m pregnant and they said they don’t give a fuck I need to watch the way I talk to people I’m so over it and needed to rant
