a genetic burden?

I am 28 years-old, female, and I've been picking my skin since I was maybe 11 or 12. My main choice has been to pick my shoulders and my back. I inherited trauma from both sides of my family. Both my dad's parents suffered from depression and anxiety and my dad's dad was abusive. My mom's dad suffered from alcoholism and was abusive with his children. Neither of my parents sought healing before they had children. I feel like I was handed such a heavy load to carry. I've been through therapy, acupuncture, and I exercise and eat healthy- but the skin picking habit hasn't dropped yet. I feel like no matter what I do, there's a pocket of shame at the core of my being. Sometimes I'm afraid to have children because I wouldn't want them to carry the weight that I have. Even if a person is genetically predisposed to be anxious, can the work I do on myself prevent my children from having to deal with all the crap?
