I have found guided meditations on YouTube extremely helpful. You would have to find a person's voice that you find non threatening, because if you're paranoid like me you might think that they're going to try to place something in your mind that you don't want. PowerThoughts Meditation Club is my favourite. The Let Go meditation was the most helpful to me. After doing meditations I tried to get rid of my hate by seeing everyone as their inner child. If we see everyone as a defenceless little child that's been hurt into behaving the way that they do, it makes it so easy not to hate them.
