Hugs hun, the exhaustion is so hard to handle. DD used to curl and clench her little hands into fists and curl her toes when being fed (boob, bottle and solids)! I also was questioning everything I did. One wise soul once told me I needed to stop thinking about and trying to get y bub into a normal baby routine as it just wasn't going to happen - it would just stress me out further. I ended up with PND, so just watch yourself because it really snuck up on me!
