Fed up with husband!! *RANT*

Granted, he works all week, Monday through Thursday 6am to 6pm & we're in WV & he works with the power company so he's been working from around the clock since last weekend since the flooding happened. He worked regular hours this week. I have a 7 year old step daughter, Nevaeh & my 8 month old daughter, Chloe by myself all the time, no vehicle & stuck in the middle of nowhere with nobody to help me. My mom lives far away & won't even come visit & I have no other family. Anyways.. my 8 week old has GERD & doesn't sleep all night.. I never have time to nap during the day because I'm constantly trying to keep my step daughter preoccupied. He got home from work this evening & we were watching TV & Nevaeh was throwing a fit because she couldn't find her favorite monster high doll & Chloe's acid reflux was acting up & she was inconsolable. He got an attitude with me because the baby was crying & he couldn't hear the tv & I was walking back & forth looking for Nevaeh's toy so she would stop throwing a fit. After I found her doll, she settled down & he made the comment that "it took me long enough" smh. Keep in mind, I haven't slept maybe but 2 or 3 hours all together in the past 4 nights. I asked him to please hold Chloe so I could take a shower because I'm using the vehicle to take Nevaeh to a dentist appointment at 7 & Chloe has to be at the doctor at 9. Which means I'd have to get up at 5 & start getting everyone ready because we live an hour & a half away from the dentist. Both kids still needed a bath & it was already 8pm. I felt so overwhelmed.. but he looked at me & said "no, you f***ing do it..I worked all day!" Umm..so what??? I'm here all day alone with no help with these two, never get any sleep.. I even started staying in the living room with the baby so he can sleep at night. I bet if I worked a full time job, I'd still be the one taking care of the kids..same as now. Idk what to do.i even said "it's a damn shame you can't even help me with YOUR kids." I swear.. he comes home from work, sits on the toilet on his phone for about 45 minutes then takes his dinner in the bedroom to eat & then sits on his phone until bedtime..or calls himself watching TV when he's holding the remote but on his phone. Every single day. It's always the same. Every once in a while, he'll take Nevaeh to the creek to fish or lay Chloe on his chest. But while he's doing those things, he finds a list of things for me to do.. he'll take Nevaeh & leave me & Chloe here & tell me I need to do dishes or sweep or wash him clothes..whatever. Or if he's holding Chloe, he says I need to clean Nevaeh's room or keep her occupied. I never get a break!! I don't ever ask for anything.. i was out of pads for over a week & too scared to ask him because every time I ask for anything, I get my head bit off!! I'm at my wit's end.. sorry. I just really needed to rant!!
