Fussy 1 year old. Help!

So my daughter recently turned 1, and lately its getting to a point of a frustration with her because she has completely turned into an angry baby. She is extremely fussy, she fights her sleep at night, shes crying through the night, starts off as a whiny cry and then comes the screams. We make sure her diaper isnt wet and she always has a bottle before bed but she just wont stop crying. Honestly we dont know what to do anymore. Is anyone else going through this??
