Stressed. Help

I’m having a rough couple months. My husband started a job as a general manager and no joke he’s never home. Most days are open to close. Then when he is home we have non stop appointments. We have a special needs son. I have no family help since I moved closer to his family and no they don’t help they only take my 2 older kids and only on their terms. I have 4 altogether. I try to manage cleaning up,taking care of the kids and appointments. But it’s nearly impossible. I’m not allowed to take my other kids to my sons appointments cause of covid so I need someone to watch them. My house is falling apart. We have pets that we got before my husband got the full time job and I wanna rehome them so bad. He doesn’t. I don’t have the time to care for them plus the kids. He did most of the caring for them but now he’s never home I’m doing it and when I ask him to do stuff I get you never spend time with me. Which tbh we don’t cause we don’t even get a date night cause we never have a sitter for all 4 kids. I know he’s stressed and I am too. I also just found out I’m pregnant. And I’m so exhausted constantly. On top of all this crap my youngest daughter only ever wants her dad she will scream and throw herself on the floor till she gets him. I know I have so many problems in one post but how do people handle all this I fell asleep I should say passed out sitting on the floor doing laundry. I am pushing myself till pure exhaustion to try to get shit done. On top of all this I never get even 5 mins for myself. I’m morning till night. Sorry I keep adding but now my 2 oldest will not sleep in their own rooms and I’ll be honest I can’t fight them to stay in there anymore I can’t keep staying up till ungodly hours of the night to make sure they stay in there. Tell me it gets easier cause I truly can’t take much more. Everytime I try to explain how I feel it escalates to arguements with my husband. He’s a good guy he truly is. Even him taking this job was for the purest reason. I just can’t take doing shit alone anymore
