Dont force it. Let the pup learn that you are not going to hurt her. It may take some time but don't give up. Just sit on the floor in the same room with her and let her react at her own pace. Don't try to engage her, just her work herself around you. Also, you may try being the one that feeds her. Don't expect any fast response when you do feed. Just be consistent and let the bond develop between you and her on her schedule.
