Hello, I am an intermediate sorceror and i may be able to help your friend. You need to enchant a protection spell/ritual. I can provide a few examples. I hope im not too late.
1.You can draw some pentagrams which are basically stars and hang them around her. make sure they are not upside down. that will bring satin and she will be cursed even more. After you have performed this step, make her imagine a white circle and her inside of this. It will keep God and his angels with her.
2.She may also chant the following. "By the Dragons might on this (month)'s night, I call to thee to give me your might. By the power of three i conjoure thee to protect all that surrounds me. SO MOTE IT BE! SO MOTE IT BE!" You should say it with her so it has more effectiveness.
I hope I have helped
