Iam... I was diagnosed with Major Depressive Disorder as well, when diagnosed with my PTSD... and my little valium experiment seems to be backing what the experts are actually saying about PTSD depression. Its mood based depression due to the anxiety, not chemical depression.
I just had a quite severe down period for the last few days, and every other time since being diagnosed, I would get extremely depressed... this is the first time I actually didn't get majorily depressed as a result of PTSD hitting me, and instead I felt minor depression at most, nothing that even made me want to eat.
This is not a debate about SSRI's or such. SSRI's will work for some, but there has been an inherit issue that treating PTSD with SSRI's hasn't been working as well as pharmaceutical companies and positive studies published would have you believe. If you read the references in the chemical imbalance wiki page, you will see that when subpoenaed, they actually found the FDA had been holding out publishing negative studies about SSRI's and publishing only positive results. It showed FDA bias in publishing pharmaceutical results. When reviewed, SSRI's actually have more negative results than positive, therefor, backing what experts are saying with PTSD, SSRI's are no longer the preferred treatment option because they believe why they don't work is because the SSRI is creating an actual imbalance within the bodies natural chemicals, thus creating a depression that is chemically based, where PTSD is creating a depression that is mood based.
By targeting the anxiety, being mood, their finding that alone removes the depression effect.
After just trying this now for myself, I will confirm with my own little trial, their on a winner with this strategy IMO. Jimmy actually tried the same thing as what I am trying here, suddenly his overall results with depression have also improved and the residual anxiety that creates worst anxiety, then a mood based depression.
SSRI's where never given as first line treatment based on any real fact for PTSD, only the theory published by the pharmaceutical companies themselves based on the Pax Medica model, which neuroscience has now empirically concluded as total nonsense. Technology is allowing medicine to conclude far better findings than biased theoretical models only from a pharmaceutical company who have a little bias, topped off with the FDA itself not publishing an overwhelming basis of negative results for SSRI's vs. the claimed positive only published results.
Because they found SSRI's to treat both depression and anxiety, they theorized that this was an excellent all-round medication for PTSD... but the facts from neuroscience are showing vastly different results, with the majority of PTSD sufferers not showing any type of chemical depression, which leave mood depression. Biological depression is not treatable, period... so if you have that, its only treatment is healthy living and cognitive exercise. Very very rare though.
There is never going to be one solution that fits all.... it just won't happen. But the majority have been lied to that SSRI's are the viable option for PTSD, because there not, and the experts and gaining significant momentum proving this by finally looking outside the box due to neuroscience. Treating the anxiety will become the majority treatment for PTSD in the coming years, not treating the depression via an anti-depressant, often making the depression worse as a majority basis.
