Parenting still matters. Parents shape who we are. So often in therapy I see the resistance, the walls go up at the mere mention of someones past or up-bring. They do not want to leave counseling blaming their parents for their issues or problems. It’s not about blame though. Parent did the best they could with the resources and knowledge they had at the time.
Of course we want to say that we are responsible for how our lives turned out and the bottom line is that we are. However your parents can and do help you understand most of your conditioning and the way you see life. How could it not? You spent a large portion of your life living with them and heavily influenced by them.
