PPD??

I love my son, he's 5 weeks old and absolutely adorable... but I can't bond with him. I look at him and he's not "mine" does that even make sense? I feel like a crazy person. How can I not bond to this tiny, amazing human I created? He cries and I feel absolutely worthless then I get mad, why can't I soothe him? Why am I such a shit mother that I can't soothe my own baby? This is like parenting 101 fucking soothe your child. I can't sleep. I force myself to eat. Usually resulting in me getting sick after. Some days are amazing and I just stare at him all day.. other days I can't even look him in the eye because I'm a failure. I'm a bad mom. I'm so impatient how can I handle when he's teething if I can't even handle a little fussy baby because he's overly tired? Is this PPD? I feel completely broken, this isn't how a new mom should feel....
