I don't think Jack Trimpey is anti counselling etc... he just sees that as separate from the addiction itself. If you find that after not purging for a while that you still feel bad then maybe counselling would be an option, but you don't need to uncover the reasons you do it in order to stop doing it. Maybe encourage your dad to read the RR book so he understands how you are approaching this and maybe he'll cut you some slack x
