Help! Puppy is driving me nuts!

[Pennymom]

We got our 10 week old puppy 2 weeks ago and I am having a rough time adjusting. I have worried a lot about whether we should return her to the shelter. I have had a lot of stresses in my life in the past couple of months but particularly in the past month and I worry we got our puppy at a vulnerable time. I have so many questions..... we crated her from day one but she still cries blue murder and whines and cries several times during the night which results in us getting no sleep. What should we do? She currently sleeps in our room but I wonder if we should move it to another room. Should we be letting her cry it out every time? Housetraining... should we be getting up in the night to let her out? Otherwise in the past day she is showing some small (very tiny) signs of "getting it". Biting.... she bites everything and everyone. What to do? I am trying everything. Anyone with puppy experience and advice that works please help! I have had many days of tears worrying about whether we should return her and the stress is having a major impact on me.
