Resistance/cognitive dissonance – believing new thoughts

I’ve really immersed myself in understanding what my current thinking is about every area in my life and then figuring out what the new thoughts are that I want to start thinking on purpose. As I go through this, I’ve noticed that I’m feeling unease and resistance in my body when I start to think/absorb the new thoughts I want to believe in my life. It’s like my body/brain doesn’t want to let go of the habitual thinking! It’s crazy! I think if I’ve overwhelmed my brain with too much change at once. I notice how often my brain goes to automatically thinking negative thoughts or being judgmental. I’ve also been feeling kinda down because I’m seeing how negative my subconscious mind really is!
