Anthony- in other articles, you say the brain chemistry problems can never be reversed. Does that mean if you need medication to cope, you'll probably need it forever? Even after the therapy part is over? (I'm not on meds now because I'm hoping to get better without them, but if feeling like this is forever, I might reconsider.) How do you reconcile your statement that we shouldn't need the forum after two years, with the statement that PTSD can never be cured, but only coped with?
Information is also old and outdated.
Due to neuroimaging, there is no chemical balance, or imbalance, to begin with. It is also becoming quite proven that anti-depressants are actually a hindrance to PTSD treatment, not helpful, which means SSRI's. Many physicians are leaning away from them and more to just medication that treats the anxiety. SSRI's are an anti-depressant used to treat anxiety as well... and seem to only cause more issues than good from current research data. So not being on meds, is more than likely helping you at present.
Therapy is a process... it depends on severity as well. The average time frame to heal trauma is 12 weeks of therapy. That figure is low because the majority are minor issues. For those of us who fall into the more extreme range of things, a year of therapy + several more years putting it all into action is more realistic. Complex trauma may be in therapy for up-to 2 years, with another 2 - 5 years putting it all into action and walking the path of life to build resilience and technique.
Whilst in therapy, you are constantly being provoked, simple as that. It isn't until you remove it you begin to see results, and that applies to only if you're putting into action what you learn, and that the therapy is good in the first place. There is no one way to achieve the aim, and there are many many factors that hinder the process uniquely for each person. If all you have is one session a week or fortnight with a therapist, then it will take time.
Some people attend 1hr of therapy a week or fortnight, then do little to nothing inbetween. That is not going to achieve a great deal trying to heal PTSD. My interpretation of healing, would be a person committing themselves to a good 10hrs+ per week of self hard work. One hour of therapy, the rest learning and implementing, pushing themselves and working things out on what happens when they do x, then how to counter it... then go practice it, which is what exposure therapy is.
There are other constant stressors within lives, ie. employment, family, relationships, etc... they are the big ones, and there constantly adding stress into your internal cup.
Whilst some people may want to jump on this next statement, it is not a broad application, but does apply to some people, which is denial and they need to snap out of. Some attend therapy, do one hour of work on PTSD per week, then spend the rest of the week trying to avoid PTSD, distract themselves from it, suppress everything that comes up, etc etc. They get triggered by something, and instead of hitting that trigger hard to desensitize themselves, they avoid it instead, adding it to become a constant problem that will just later need to be dealt with. It is common to see people in complete denial whilst in therapy, and they use the attendance of therapy to tell themselves they are doing something, then do nothing the rest of the time except complain about the symptoms, until the next session, when they let all those complaints out to the therapist, maybe poke at one or two things, then there out of time again, repeat cycle.
