Can't take being pregnant anymore

I'm 34 weeks pregnant with gestational diabetes the baby is weighing around 7lbs already and I cant take it being pregnant anymore. I have severe pgp that my midwife is doing nothing to help it. I have to put up with it. It's so bad I'm literally bed bound as I'm in agony and there is nothing that help. I'm short and I'm carrying a really big baby people have thought I was carrying triplets. I'm constantly feeling sick and have loads of pain and discomfort. I havnt slept for 3 days as its been bad. Everyday I'm crying coz its to much for me and I still have to wait 4 weeks before they will induce me or a c section I cant wait any longer I just want the baby out
