Our behaviours try to help us - YES! Even when they hurt, even when they don't seem to be working.
If we only want to fix our behaviours, go to Google - there are hundreds of answers there.
If we want to understand ourselves, learn, appreciate the amazing person that we already are, then my suggestion is that Counselling Phil style - connection and curiosity - may give you the understanding and tools to be able to grow and have a healthier life. Let's change the "need" for the behaviours, and they will change themselves. We are not a diagnosis - we are a human being experiencing life.
A quote from Pema Chodrin - "The purpose is not to change ourselves, rather to make friends with who we already are".
Sometimes we can just get a hint of who we are - and need a safe way to find it.
