Ppd? Help... UPDATE

My baby is nearly 8 weeks old. When he was born I had baby blues, literally would cry over anything and everything, I also had really bad anxiety in the first couple of weeks. I literally felt like I would accidentally kill my baby, but that faded away before the 2 weeks were over.

Since then I haven't been overly emotional or anything but I'm CONSTANTLY angry at everyone and everything. It's getting to the point where it is affecting my relationships. Recently it's making me feel negative emotions towards my baby also. I mean from the day he was born, I have never felt 'love' for him. I've heard of this amazing 'motherly love' your meant to have for ur babies but ive never felt it and it makes me feel like such a shit mother.

Is this normal? Will it go away? Or do you think I might have ppd?

Update:

Had my Health visitor visit yesterday (I'm from the UK) I spoke with her about how I was feeling and she told me about some postnatal mental health groups I could join. She also told me to make an appointment with my doctor to make an actual diagnosis as she doesn't have the qualifications to diagnose me but she believes it may be ppd
