So disappointed 🤰😓

So I’m 36 weeks pregnant and for the last 3 months it’s been unbearable to eat or drink anything including water! I went to see my GP originally at 24weeks pregnant about my mouth to be told it was thrush and given medication for 2 weeks, well that made no difference so I went back to see another GP who diagnosed the same but gave me a different medication that also for 2 weeks didn’t work. At this point I’m losing the will to live because for a month I’ve been unable to eat anything other than salad because my whole mouth is red raw, full of ulcers and stings to even open it so I see a 3rd doctor 2weeks later due to no appointments who tells me it’s vitamin b12 deficiency and iron but I’ll have to wait a further week for bloods! I have the bloods and someone is supposed to call and tell me if something is wrong, I get nothing at this point I’m ready to chop my tongue out of my head so make an emergency doctors appointment with a 4th doctor who tells me I’m completely deficient in b12 and iron, also anemic and could possibly have a liver stone as my liver markers were high in my bloods too so I’ve got to have further bloods taken to check my liver then possible scans on my liver to ensure it’s working properly! Surely doctors should know these things are common in pregnancy and have tested for it 3 months ago! I’m so mad I’ve been left to suffer for so long especially with getting different doctors each time. Also the deficiencies can cause spinabifida and problems during birth and even premature labour I’m beyond angry that it’s been left so long. What does everyone think?
