Rachel, is this the first dog that you've owned? You seem awfully frustrated. It's only been one week since you got Sadie, you should still be in the honeymoon phase!
Sadie's just being a puppy. As the others have said, this is the price that you pay for taking her from her Mommy too early. I went through this with Missy, but I enjoyed every moment of it (honestly). I've *yet* to feel frustrated or upset with her and she'll be 1 yr old next month. Maybe there are other stresses in your life that are getting you so upset and it's not all Sadie.
Every single problem that you are dealing with right now is "normal" for a puppy this age. I personally didn't fight the sleep issues, I just brought Missy into my bed
I've had a restful sleep every night since! As far as the barking/growling...are you dealing with her in a calm, relaxed frame of mind? Because if she can sense that you are uptight, she won't see you as pack leader. Try to calm yourself down, and use the tools that you've learned here on YT. Potty issues? HA! I was very lucky with Missy, she trained right away BUT I have heard several people on here say that their Yorkies aren't trained until a year or longer. So be prepared!
Try not to worry so much, everything will fall into place in the next few weeks. It will just take time.
