30 weeks and feeling defeated

I'm so done with this pregnancy. I just can't do this anymore. I've had such a rough pregnancy, first I had hyperemisis and now that it's finally went away and I thought things were going great, I find out I'm extremely anemic, and I'm giving birth at a birthing center so if my hemoglobin drops any lower than what it is now I can't be in their care, my baby is measuring 4 weeks bigger than I am so I have to go get an ultrasound to make sure he's okay, the supplements they have me on for iron are making me sick again and to top it off we don't have insurance and have to pay for all of this out of pocket and we just found out the medical loan people were getting the loan to pay for us to give birth will only let us $500 and we have to come up with the other $4000 by the time I'm 36 weeks and also pay for the extra ultrasound I need and more blood work to make sure my hemoglobin is going up. I mentally can't do this anymore. does anyone have any advice?
