In need of advice…

I was a stay at home mom for almost a year before I started a new job. I work long 12 hour shifts starting at 4am about 4 days a week. My husband is a stay at home dad since we don’t have a babysitter so I’m the main income. I found out I was pregnant 4 weeks ago (currently 8 weeks). I’ve been miserable. I’m depressed, exhausted, nauseous, irritable, just a nightmare to be around since taking this job. It takes time away from my daughter and I feel like I want nothing to do with her since I’m always so exhausted. I feel guilty like my husband is a single dad tbh. He does absolutely EVERYTHING for her. I don’t even feel like a mom anymore and it kills me cause of the way my new job has effected me along with this pregnancy. I’m contemplating on quitting. My husband said he would start working and I can stay home if that’s what I think is best for me. I just feel so bad quitting cause this is a good career type job. I just hate the hours so much. Idk what to do. Do I make my mental health a main priority? Or do I stick it out to make money for my family. I’m so pulled. Just need someone else’s thoughts.
