Stressed

So I’m on a high risk pregnancy for premature birth, I have two other kids. Anyways my husband’s boss just told him that he’s gonna have to work more than 45 hours now and have to work 6days with one day off. I’m not sure how to handle this. We hardly see him now, I’m thankful he has a job but I still need him through this. I most likely will be on bed rest because my placenta is attached wrong and if I have anymore bleeding they will put me on bed rest. I also have to go every week 1.5 hours away for shots to help prevent premature labor, I’m always dizzy and have fainting spills and can’t drive that long by myself. Plus every 2weeks for ultrasound in the same place but they won’t put them in the same day.. My family is not trusted with my kids(I was abused by them). My husband’s only family that could possibly help is 90 and shouldn’t be helping. I’m stuck at what to do, I still have to carry my daughter around at times as she’s one and her legs get tired easy. I still have to manage to get my son to and from school, do shopping and normal life things. On top that we are moving, and that means on top of everything else I have to pack. Ugh sorry I needed somewhere to vent or let it all out, I don’t know what to do at this point but try to go with the flow of everything
