That is a useful coping strategy for a child but if you can get away from the abusive family or whatever group, as an adult you absolutely can be free to deal with the effects until you know yourself as a free, powerful, and normal human being, with a life you are contented by.
The experience of abuse, especially directed at oneself rather than towards everyone, can lead to an idea that one is uniquely, shamefully bad, cut off from others, abnormal in an essential way, as opposed to the idea of everyone is in the same boat, we share a common humanity etc. Normal in the latter sense is what I meant - in opposition to being on the other side of a glass from which one can observe humanity without feeling connected to it. Probably a sort of dissociative symptom.
