Hello, It is indeed very true that our life experiences do shape our being and the kind of person we become. But possibility the perception towards life experiences and our will, has a strong effect on the personhood that we carry. For you worry is not such a bad thing, may be worry will always tell you to do better and make your resolve to be a better person, a better spouse, and a better mother. Hence please try to keep your resolve and motivation strong. Please visit a clinical psychologist if you still carry self doubts. Hope this helps you. Best wishes for your health and future.
