Hello,
First off, understand and appreciate that mine is just one voice, one experience, and that I might be wired very differently than others regarding what I judge a reasoned workload concerning the efficacy of independent application. It would be heartlessly cruel not to disclose as much...
Given my history and relative isolation from the best contemporary iterations of modern psych. care and psychopharmaceutical intervention however construed, I felt (and feel) that I had to do something rather than 'just sit on it'. Therapy (at least to the extent of what I could afford) seemed unsubstantial contrasted to what I could read, whereas psych. meds too frequently left me debilitated for powerful side effects suffered, prompting me to ask myself again and again what constituted quality of life, and specifically who determines such. Not nice, but my frustrations (again - this is just one experience and not necessarily anyone else's) could hardly be contained.
In short, yes - one can facilitate the process of healing for self-care via bibliotherapy. Hazards exist for our cognitions of much, the temptation to place too much emphasis here and not enough emphasis there is an ongoing struggle for anyone in the thrall of PTSD and abusive legacies however constituted or construed. Reading can serve to demystify dynamics that otherwise embody unspeakable terror, whereas all professional one might consult were at one time mere mortal undergraduates charting an uncertain way occupational way forward once upon a time. Some will say that intellectualism embodies a defensive stance of sorts in relation to others aspects of healing that require reclaimation of emotive capacity realized only through human interaction. I don't really doubt this, but the fashioning of a fine shield isn't so bad a near-term end!
While I don't want to roundly discount the worth of professional help, there is something positive to say about embracing the task of understanding PTSD because at core it is ultimately about us and the quality of life we may secure for application. Others can inform and guide us for experience - when they are there, when such professional services can be afforded. But for contrast and consideration also know that outsourcing decision making, imagining that strict estimates afforded to a psych. practitioner as to 'how many sessions will afford sympton allieviation' etc. is still guesswork that often suits the needs of insurance companies first, and the varied needs of vulnerable clients second. If you occupy the gap between care that cannot be afforded or seems inadequate and are voicing words consistent with the intent of learning more with the aim of suffering less - please follow up and demonstrate the assertion that is consistent with a life that is both assertively and creatively led!
Try not to be sucked into the factionalism all about regarding what constitutes what, the strict definitions of so much, what this body or that extolls. Any wide-ranging study reveals that all knowledge concerning psychological trauma has evolved from well-intentioned beginnings of bright people giving their best even as they pursued different and sometimes opposing paths. Egos within the field are LARGE - hence be forewarned! The study of psychology is especially contentious, with rival schools, theorists, conceptions of right intervention, etc. equating to a certain progress - but this revealed, the evolution of the field has hardly been absent internal conflict. Let your attention and inclinations guide you, for there is no one true and right way. Psychology is fascinating stuff to read, whereas many psych. students in our schools are unashamedly embracing what is quietly identified as 'mesearch'; i.e. deconstructing interpersonal and familial legacies that have them or those they love in a twist.
Not God here by any definition, but you could do far worse than to read Bessel van der Kolk's Traumatic Stress: The Effects of Overwhelming Experience on Mind Body and Society, and Judith Hermann's Trauma and Recovery: The Aftermath of Violence - From Domestic Abuse to Political Terror. Both are fine, both are widely-cited, whereas I err towards academic sources for I don't especially like pop. psych. Please - be well and know that nothing here trivializes what cannot be anything less than a long process of healing.
