I can't handle this

I have PND and My daughter is 8 months old and things were getting better. In the beg hiking I didn't want to hold her or play with her just wanted to feed, shower and dress he and put her down. It gradually got better. Until she started waking 10 times a night and now when she is put to bed she screams and screams and screams only stops if I pick her up this goes on for sometimes two hours a night. Now it's gone back to just not wanting to deal with her. But of course I'm going to but I'm hating my life more and more I'm seriously so sick of being so exhausted. Day in, day out
