I am sure I fell short especially in my military career since I was stupid enough to get hit by an IED (after all my training I should have known better).
I strongly object to you thinking that you could have avoided that IED, femaleveteran! It is no different from any of us being hit by a bus we didn't see coming. Sure, we've had the training, and we're watching out for dangers, but sometimes, no matter what we do, WHAM! Stuff just happens.
I have read your posts and you are a smart, capable lady with a lot to offer. I'm sorry your career has been ruined by this accident. The IED should not have been there in the first place, so that is certainly not your fault.
I know a symptom of PTSD is that we think we played some part in it, or are somehow to blame for what happened to us. That is one of the LIES that this disorder likes to tell us. Just as we heard LIES from important people in our lives, that we now replay over and over and over when we are not feeling 100%.
The way to combat those lies? (And I like that word combat here because it is a battle for sure.) We start telling ourselves the TRUTH about us. And we let others tell us the TRUTHs that they see about us. Some people use daily affirmations and that can work too. Tell yourself every day, over and over and over again, "I don't have to be perfect to be loved." "I am smart at a lot of things." "I am a good friend to others." Whatever you need to overcome.
Put a little sign up in a few places where you can see it that lists your wonderful qualities, or phrases that are positive about yourself. That "motivational b.s." as some people call it has been mocked in film and TV, but who cares?
If it's stupid, but it works, it's not stupid. (Maybe you heard that during your military career, I certainly did in mine.)
Unlearning those negative messages is all about reshaping your thinking -- finding a new method of thinking about things as Anthony says above. When you hear that message "I have to be perfect to be loved", surely your mind can pop up the very popular saying "Nobody's perfect." Those two thoughts are incompatible -- if nobody's perfect and you have to be perfect to be loved, then nobody would be loved. And since some people are clearly well-loved, despite being imperfect, then it holds true that you don't have to be perfect to be loved.
When we're kids, or in a vulnerable state, we often hear messages that are untrue but our mind holds onto them, for whatever reason. In psychology that's called the "sleeper effect". That (wrong) message from a source we think we should listen to becomes very persuasive, and it gets a foothold in our brains, coming up again and again when really we should just ignore it.
Like a bad weed in our mental garden we have to root it out. Replace it with a positive message instead (find the opposite message) or acknowledge that the source (if you know it) didn't know what they were talking about.
As is true with many aspects of PTSD, being able to identify it is the first step to managing it. Be alert for those negative messages -- maybe make a list of them so you can recognize them -- and then systematically eliminate them by replacing or reshaping them.
One of mine: "You're too hard to get along with."
Source: My mother loved to tell me that. Maybe I just didn't get along with HER.
My replacement: "I'm an easygoing person everyone likes."
My re-shape: "I may be hard to get along with
sometimes, but that's because I cannot tolerate fools." (Take THAT, Ma!)
