No. Authors - and internet forums - will not suffice.
"trauma cannot be healed alone" meaning it can't be healed by the one person, without another human being to participate in the healing. Deli I don't say that someone can lay hands on a person and heal them; the healing has to come from inside; but there MUST be another person, if it's trauma.

The healing happens in the relationship - because the trauma person (I hate the word victim) has a shattered trust, and trust has to do with OTHERS and trust can't be rebuilt by one's own determination. You can't stand on a rope and pull yourself up. The traumal client/patient tests and tests and tests the therapeutic relationship, and there is rupture after rupture after rupture, and each rupture must be repaired so the work can go on; and it is in the repairing itself that the healing occurs; the trauma client/patient learns that not every rupture is catastrophic, that relationships CAN be repaired, and that trust can be given (not unwisely, not indiscrimantely of course, but that was so before the trauma too).

If you have been reading Treehouse's posts these past two years you will see that this is all true. sorry, can't do it with a book, or with cyberfriends , however much these can comfort and enlighten.
