PTSD is caused by many reasons. There is nothing to be ashamed of. The illness has existed since humanity's dawn, but has more recently come to light in the eyes of the general public much more because of war veteran's returning from the middle east. Think of how many WWI, WWII, Korean War,Vietnam Veterans, and others suffered and are suffering from ptsd, and then it was only known as "shell shock". Thankfully, the media over the last decade or so has really brought attention to this illness--both military and civilian related. Almost all of ptsd is caused by the actions of other humans--whether trying to kill you in war, through assault/abuse, or you being personal witness to an atrocity committed--willingly or unwillingly--by our own "species". Granted, some ptsd is caused by natural and other events, such as weather disasters, death in the family, etc. But, that is more rare. Whatever reason you may have it, I say "own it". Accept it as being a part of who you are, and live with it, day by day, as best you can. Meaning, you have earned your stripes from simply having it, have been and are going through hell, and have just as much right to express your feelings concerning the disease as anyone else.
