Thought download unearthing negative emotion


I did a thought download last night that ended up focusing on a lot of thoughts (and resultant negative emotions) about things my mother said to me as a child and related negative beliefs I have about myself to this day. Today I found myself spinning in those thoughts and negative emotions with a lot of self hatred and negative self talk. This hasn’t happened to me before. Is this a common occurrence? I’ve never experienced a thought download “hangover” like this before. Does it mean I really touched on an area where I need to do work?
