The short answer is ‘yes’ - but only if you really get to grips with what is actually causing it, and understand what you have to do to overcome it.
There are many different types of psychological trauma that all of us experience all the time. If someone treats us cruelly, embarrasses us in public, steals from us, hurts us (physically, emotionally, financially, psychologically…) - all of these things can cause a psychological trauma to the person that’s experiencing them.
The intensity of that trauma will depend on the following main factors:
So, assuming the worst case scenarios across all categories - it was a repeated, deep hurt that was inflicted by someone very close to you, and it happened at a very inauspicious age in relation to the developing brain - HOW THE HECK DO YOU GET OVER IT?!?!?
The first thing to say is that the brain is plastic, and just as it was ‘trained’ or conditioned or wired to react in a traumatised fashion, it can be re-trained, re-conditioned and re-wired to start to act in a more helpful fashion.
Self-education is a very important part of this process, and I highly recommend the following books:
Pete Walker’s: Complex PTSD - from surviving to thriving - is a great, easy to read book that really sets things out very clearly, and gives a wealth of concrete advice and practical tips for HOW to start retraining your brain.
You can see his website here:
Pete Walker, M.A. Psychotherapy
As a starting point, take a look at his 13 steps for managing flashbacks (which I ‘riffed’ on to do the following infographic:)
Another excellent book to read, although some people find it a little ‘scholarly’, is Bessel Van Der Kolk’s The Body Keeps the Score.
This article is a good introduction to the book’s main approach:
The lifelong cost of burying our traumatic experiences
The key thing to understand is that trauma changes the physiological processes in the brain, and causes people to become oversensitised, jumpy, ‘stressed out’, overwhelmed etc.
Trauma is often ‘stuck’ in the body, and has to be viscerally released, not just talked about endlessly for years in therapy.
I’ve pulled together a whole bunch of suggestions that tackle psychological trauma across all three levels of body, mind and soul on my website, and you can see that here:
c-ptsd 101: I've got c-ptsd! now what do i do to get rid of it?
But the short answer is that it CAN be overcome, once you know what actually caused it, how it’s really affecting you, and what types of things you really need to do to overcome it.
