Halo for family

I ordered the unhex halo healing candle and I am wondering if I can use it for 3 people, myself, my mother and sister? My children seemed to have escaped whatever had plagued my immediate family so they are good. But for us (the ones above) not so much. When I think of all the crap that has befallen us I get very angry, how can I block that anger from coming through? I don’t know how to even word my request without sounding like a demon possessed hell-beast. Any guidance would be greatly appreciate.
