Could I have ppd 7 months after birth?

I don't know what to do. I get so angry with my 7 month old just for crying. I yell at her and it makes me feel horrible. I cry and apologize but then I turn around and do it again and again. I love my daughter so much but I somehow hate her sometimes. I don't feel connected to her . She would much rather be with her dad anyway. He makes her smile and all I do it make her upset. This doesn't feel normal. I would rather watch TV and lay by myself in bed than snuggle and play with my daughter. Is this ppd or am I just a terrible mother?
