Traumas are ubiquitous and range from milder forms to more severe forms, and depending upon your temperament, they can be reconfigured into sources of growth rather than pain.
Some people are almost completely unaffected by traumatic events, and don't need any help in getting over them and learning their lessons from them (if any), whereas the same traumatic events utterly devastate others. But those in the middle can be tinkered with, and made to lose their unbearable stresses, and grow in a desirable way in spite of (or precisely because of) their traumas.
Pain and stress is the prerequisite to growth, after all; too much, and you get injured and die; too little, and you rendered enfeebled/weak and can die all the same.
How much trauma you can handle depends upon your individual circumstances -- your genetics and environment. And the direction of growth also depends upon your individual circumstances. A psychopath can be said to be "growing" a rape slave as he molests a young girl, for example, and traumatizes her as such. Perhaps this is not desirable growth, but it definitely works in the end, as the girl grows into a whore. The concept of "post-traumatic growth" is valid.
