Some of the benefits I’ve experienced are:
– remission of depression
– less anxiety
– more energy
– confidence to ask for what I need and want
– confidence to express disagreement
– able to show up for and be more comfortable in professional, personal and intimate relationships
– not losing hours or days to being stuck in anxiety & depression
– dramatic improvement in the quality and quantity of my work as an engineer

I wholeheartedly recommend Dr Zack Bein and the Three Pillars method of Adult Attachment Repair.
