Hello OP. My DD (now 2) was like this. At 10 months she was refusing to sleep at all without a boob in her mouth (and would wake every time it fell out). We both got no sleep; my DH also thought I had PND but I didn't, I was just murderously tired.
We tried EVERYTHING. And I mean everything. And we checked her out medically too. And as DD refused a bottle and also didn't sleep during the day, and as I also had a DS to look after, I was beyond exhausted. So after I had a (very public) breakdown one day, DH took her into our bedroom (her cot was attached to our bed) and banished me to my DS's room. We stopped the night feeds there and then, just so that I could get some sort of sleep. She went mental, but he stayed with her so that she wasn't alone. And after a long, long time she learned to go to sleep.
There were no quick fixes. We have had to do long bouts of cc, and then when DD has "relapsed" months later, we have had to do it again. I don't like cc. But my DD didn't respond to anything else and as my marriage was on the point of breaking down, my DS was suffering and so was my poor DD, who was angry all the time because she was knackered, cc was our only option. It took months but she gradually got better, and as she started sleeping she also became a happier baby, and me a better mother.
So in brief what worked for us was to stop night feeds, to hand DS over to DH at night (and later to take it in shifts), to have a plan between you about how you will handle it when she wakes up (consistency is key), to try cc, to accept that change would be gradual, and to ask other members of our family for help.
I really do feel for you. If you haven't had such a poor sleeper I don't actually think you can understand just how awful it is - well, I do understand. But it will come to an end. She will learn to sleep. Things will get better. And feeling like you hate your baby is something I remember - feel guilty about - but the level of sleep deprivation you are going through messes with your head. Devise a plan with your DH, write it down and stick to it. Good luck xx
