puppy crying whole night

I got my GSD pup 5 days ago and she won't let me sleep at night . I have reached my breaking point because of the sleeplessness. she sleeps in the basket beside my bed and still cries most of the night . I sometimes feel like returning her to the breeder I got her from . she is a 5 week old puppy .

should I let her sleep in my bed ?

please help
