how can I get baby to sleep in own bed

My daughter is 11 months old and she refuses to sleep by herself at night.. I co slept for awhile and then stopped and she was doing good for awhile, but now she just won't sleep in her own bed now... she will sleep alone in her bed during the day.. I want to fix this.. so I let her just scream or what.. seriously need help.. also I think she's going through seperation anxiety... 😔
