I'm very new to spell casting. Recently, I was wronged by someone and would like to cast a revenge spell against them. I don't want to kill them or cause them physical harm at all. I would like to haunt them with what they did to me every single day for a period of half a year, which was how long it too this to unfold.

Do I have to be cleansed of negative energy to do this? Furthermore, how would I do this? All I feel that I'm asking for is justice...nothing more and nothing less. Advice?
