Obessesive compulsive dis. With anybody!

Her problem is she is afraid of God Shaneeswara or some crows like that. She does not use any black items, clothes etc. She is facing this problem from almost 15 years. She does not like to talk with anybody regarding this matter(that much problem severity is there). She is not sleeping well. Some times she does not sleep for whole night. I am not able to know what to do regarding this matter. She tells she is getting that bad picture/image again and again disturbing her and not feeling comfortable. She alone cries and feels to stay alone at that time. She don't want to go outside and don't want to be with anybody.we recently got married 4 months back. We are not able to enjoy our family life properly due to this problem. Sometimes this problem severity leads like she tells she don't want to live anymore, please understand our situation and kindly help us
