New Mom Feelings

I just had my baby almost three weeks ago, my birth was awesome and she’s healthy. But since having her I feel like I’m doing nothing right. There’s nothing really wrong. She’s still healthy and she’s eating and everything. I just feel like I’m doing nothing right and I feel like crap. I know some of it is because I stoped breast feeing after I hit the two week mark. But I’ve felt so awful and clueless since she’s been born. Is this normal?
