37 weeks pregnant and don’t know what’s wrong.

I’m 37 weeks as of today and I just feel so depressed because I feel so bad. I dont know what’s wrong and the doctors don’t know what’s wrong. I feel so dizzy and shaky all the time. I black out at random times. Doesn’t matter if I’m sitting laying or standing I will start seeing little dots and everything just starts to turn black. I can’t breathe which makes everything worse. I can’t drive so it’s hard to get to my doctors appointment and my nst appointments. I can’t even shower without having my husband sitting in the toilet seat or me sitting in the bath tub which is hard to get down and back up. I also have a 11 month old at home and it’s mostly just me and her all day. I know I only have 3 weeks but I’m so scared that I’ll pass out and my baby chokes on something/falls/ drops something on her. I’m scared I’ll faint/fall and hit my stomach/land on my stomach which I almost did when I Almost fainted showering. I dropped the shower curtain and my husband ran in as I was slowly sliding of the wall. I don’t feel safe. I’m scared for both of my babies safety but doctors refuse to induce me. Because blood pressure is good blood surges is good lungs are cleared iron is good. Why do I feel like this.
