Trapped In A Voodoo Spell

I have a friend who needs my help and I don't really know what to do. She told me it was some type of voodoo or curse that was placed along her mother's side of the family. It is carried along to the first daughter of each generation. Also that the mother and the daughter can't be under the same house hold for to long or it can lead to death. She says that that is why her father had to take her and her sister away. I did not really believe that that is why her father took her away but I guess it is nicer to believe than they split up because they could not stand each other, or just liked someone else.

She never tells anyone about this, the only reason I found-out is because I sensed a strong and evil spirit around her a lot. I told her about my discoveries and she began telling me little by little. I began trying to help her. This I would do by listening to what she had to say and giving her advice. I helped her self esteem grow and made her into a more sociable individual. I know that when one is sad and alone that is when demons tend to strike most. It has been working and has made the attacks milder but what I want is to help her be able to get rid of it permanently even if she loses the ability to feel any spirits both good and bad. She has dealt with this all her life; she is 18 and scared of them. She does not wish to talk to her spirit guide all of this frightens her and without a spirit guide she will always be in danger.

I had once wished my powers away and they left in fact to get them back was very difficult and they are no longer as strong as they use to be for I has to start from zero all over again. I though maybe she could wish her powers away but apparently since they are tied by a curse she could not do this. This is what I need help with undoing the family curse. She does not wish it upon anyone and dose not wish to pass it on to the next generation.
