It depends on the curse and the techniques employed.This is a grey area as far as I'm aware in satanic magic - in that not much has been written.The snippets in 'the satanic Witch' may help, but you need to find out who has placed the curse and there magical ability.Once done, then you can resort to your plan of attack. I was 'cursed' or I should say, 'psychically attacked' for months on end a few years ago by someone I knew.He had been involved in the 'occult' for forty-plus years, the method of attack which I later found out some months and months later was that he had a 'image' of me and that he surrounded that image with a 'black mist'.I know,please bear with me, and that he was attacking me on a daily basis and I started to suffer with serious depression,it was no joke,it literally felt as though there was a 'big black cloud' around me and it nearly destroyed me. There is a cursing technique called the 'Black mist curse' and I'm sure that was what was being employed.
