kers, I felt the exact same way as you -- what a relief!! Because I am always blaming myself for this, even though heaven knows I don't choose it and I don't want it!!
My Dad has been through PTSD as a result of an event at work. Incidentally, he was also physically abused as a child.
Now that
I have developed PTSD as the result of an event at work... and I already had depression + anxiety/panic issues for 15+ years prior to the PTSD (and our family doctors all concurred independently that the depression did appear to be hereditary in our case) ... and I also inherited migraines from both of my parents ... Well for me, this study simply confirms what I already strongly suspected.
It's genetic, it's not my fault, and it's the way God made me.
Now since God don't make no junk, I need to figure out what's the silver lining in my raincloud.
