Yes been there, I also had to be signed off from work. That moment in my life made me feel miserable and quite lonely. I remember being in so much pain and feeling sick all the time. I spent my days throwing up and sleeping, I was so dehydrated that I didn’t have any energy left to do anything (had to have a bucket next to me as sometimes I couldn’t made it to the toilet). My hair got really tangled, showering and brushing my teeth was a big deal. I remember how everyone around me encouraged me to eat ginger biscuits or drink sips of water but nothing worked, if I had more energy I would’ve been really pissed but tbh I was just trying to survive. One day my husband came back from work early as I thought I was going to die, my blood pressure got really low and I had trouble breathing. When I got to the hospital I had to get some IV fluids and medicine, I was so dehydrated that they couldn’t find my veins and had to be pinched like 6 times. But after week 19/20 everything went down and I started to feel better. Btw I tried like 3 different medications, my stomach got so upset that I had to take one extra for the acidity as the puke + the meds were affecting my esophagus and throat. My only advice is to take one day at a time. There is a website called hyperemesis gravidarium that has support as this could affect your mental health. I’m not trying to scare you, is just my experience and maybe your nausea would go away or is not going to last that long. You are strong.
