What should I do?

I'm starting to detach from my baby. I had gotten excited for his birth. But now that he is late, my doctor went out of town and deserted me. I just had to "let it go". And I guess I let it all go. I'm not excited for his birth now. I'm just upset I have to do all the work. I'm upset about the recovery. I'm upset about starting to breastfeed. (I have another child, I know what work this is.) it was all worth it. But I'm just not feeling the "I can't wait to snuggle and take care of and love" I'm not feeling the joy I should be now. I'm not excited or happy anymore. Just exhausted and hurting. I'm worried these feelings won't go away once he is here and I'll resent him :/ I was so ready and in love. Like you are supposed to get at the end... But I guess too much time passed and that feeling had to go away :/ what should I do?
