The traumas you have experienced can influence how you raise your dog. For example, if you were raised in a harsh environment, you might decide to not train your dog to have good manners. But then your dog becomes out of control or even dangerous.
Dogs can't train themselves. If you find that you have an aversion to setting boundaries for your dog, avoiding training and necessary rule enforcement, then your dog's misbehavior isn't going to get any better through neglect. For many dogs, you can't postpone the training forever. In some cases, your dog might even become dangerous to you or someone else.
Be honest with yourself if you are going through this and seek a good therapist. There is no shame in getting help. Then have your therapist coordinate with your dog trainer to develop a healthy and workable program that is good for you and good for your dog.
