Exhaustion

Jessica
So, I currently babysit a two year old Monday thru Friday 7:40am to 4:15pm, babysit a three month old about three days a week, and I work at a distribution center Monday thru Thursday 6pm-11pm. My job at the distribution center requires a lot of twisting. 
Lately, my body is shutting down! I am 30weeks and 3days today and I don't know what to do. I want to do what's best for our baby girl but we have to pay for my maternity leave out of pocket and we have not saved up all of it yet. I also feel guilty that my husband has to stay at work till 4:30am already and I get off at 11pm. And when he wakes up around 1pm-2pm he helps out with the kids I have that day. 
The babysitting seems to be okay. But it is work that is causing a lot of pain in the front of my pelvic/uterus area. I asked my work if I change my restrictions to add excessive twisting (Already on a restriction for only lifting 20lbs or less) if there would still be something for me to do and they said they cannot guarantee it. But if they can, at least I am not doing physical work. Still wouldn't be sleeping much but the pain would go away. 
I don't know what to do. I am not sleeping and my anxiety and depression is back. My husband says to change my restrictions at work and keep babysitting. If they send me home, we still have the income from the babysitting to cover the bills. 
My husband is starting to get worried about me that I am taking on to much.  He would have me in bed rest if he could. But I want to take care of our girl and contribute financially almost as much as my husband does. 
Guilt and anxiety overwhelm me on a daily basis and I am starting to drown! I thought I was mentally and physically strong until I became pregnant. This is way more intense than I ever would have imagined!!! 
Sorry for my bummed out post 😕
