PPD & anxiety 2 week old

I thought post pardom was only when you stress about the baby, now I see it’s so much more. I absolutely love my baby and anytime I feel upset I just hold her close. It’s nothing wrong with her it’s me. I find myself breaking down at random moments for no reason in specific, Labor and birth was extremely hard on my body, so I can’t move how I want and I feel like I’m accomplishing nothing being in bed most the day. I’m having a identity crisis like if I don’t recognize myself anymore, sometimes I wonder if I’ll ever be able to enjoy me time again but then again I don’t want to leave her. I keep pumping 3 hours apart strictly to provide for her but even then I loose motivation for it and it gets so hard, I don’t like how pumping feels my breast get very sensitive and I get a “ick” feeling, my body is in pain & I just don’t feel like myself . How long dose this usually last 😔
