Emotional wreck

Set to be induced next week and suddenly the excitement of a new baby is gone. I think my body is just completely exhausted from pregnancy and I am full of anxiety and worry adding another child to our life. I don't know what's wrong with me. I felt completely different a few weeks ago. I'm dreading breastfeeding and am worried about the emotional toll lacknof sleep takes on you- even though I've been sleep deprived for months now thanks to uncomfortable pregnancy
