Losing excitement

So I'm having my baby this week and I was completely ecstatic but I don't feel like I'm allowed to be excited anymore. I got in a big fight with a family member yesterday and got told how worthless I am and how I'm a fat bitch and just awful things. I don't plan on ever being on speaking terms with this family member again and the fight is over at this point but after it I just find myself not so excited about having my baby girl anymore and I'm not sure why or how to change this. We waited for thus for so long and now I can't even seem to be happy about it anymore even though I love her so much already.
