Toss or donate one thing from your house that has negative associations with it. For example, I like my computer chair but it has negative associations because I bought it because my freshman year roomate had the same one and loved it. A few months later we had a falling out and I ended up moving out of the room. I still have the chair and since it has negative associations I should get rid of it. Bring good energy in to your house and take the negative energy out.
