I'm not sure it is possible to ever be completely healed from trauma (as in, you will totally forget about it), but with support and therapy it might be possible to get to a place where it is just an (unpleasant) memory stored away in the back of the mind, but no longer elicites a trauma response.

But I would think that would largely depend of the type of therapy used and the quality of the healing relationship between the therapist and client.
