I don't believe anyone is saying that at all Monarch... quite the opposite. The way in which we got our trauma is unique from person to person, as I pointed out in my original example. What people tend to do though is believe they will find more comfort from someone who suffered the same, or close too, as they did, which is far far from the truth. PTSD is a neurological change within our brain, classified as an anxiety disorder, and how you got it is irrelevant to how you feel to another who also has PTSD. The symptoms are the same, and that is what bonds us already... when people try and find someone who has suffered the same as they have for understanding, is often causing more anxiety firstly trying to find them, then discovering that what they hear from them actually does them worst mentally, thinking their trauma is lesser than the other, or the other is lesser than themselves. All bad when the original concept was to seek like support.
PTSD is what we all suffer, and that is the goal in order to heal. Uniquely people must heal the way in which they got their trauma, that is what a counsellor is for, but yes, healing our trauma is part of healing PTSD, but that doesn't mean we have to go and only find support from those who suffer the same or like trauma.
Hope that clarifies what this thread is about, and the comments made.
