Hi. I only realised that I had trauma linked to an experience of health issues that weren't picked up for a while aged 20. It was an invisible illness and I was dismissed fir a while by gps and indeed myself - it was my fault; I wasn't working hard enough, being fit etc, giving into laziness.
I still deny how hard that time was to myself as I don't feel I do qualify to say I had ptsd but I do - I'm getting flash backs as I type. One was that I didn't deserve to live as I was failing but that suicide was an ultimate failure. I was caught in a no-mama land.
I've had to fight for 20 years to fully get the right info and treatment (mainly understanding it enough to be able to work with the gp to make sure I'm on top form) - which has opened fresh wounds each time.
In fact some of what has been describe here I've only just worked out applies to me too - re-experiencing / avoidant stuff.
I had CAT therapy (can't remember what it stands for) amazingly on the NHS. It was all triggered during my pregnancy as once again I had to be my own dr and the post natal anxiety was nothing to do with pregnancy- it was trauma. At a taking therapy I went from reasoned calm talking to crying / near hysterical and back again as thoughts / threats entered my head.
Being dismissed is a huge trigger for me. Interestingly my therapist linked it to specific incidents in my childhood also, again an unusual illness where I wasn't believed (mesonteric peritonitis - I think) and had to put up with the pain and told myself I was weak.
My biggest breakthrough was when I read about trauma - a normal reaction to an abnormal event - that it made sense. And that a natural reaction is to want to help others in the same boat.
And I developed a visualisation method to help me distract in moments of high emotion / flash backs (colour spotting, visualise a garden on the top deck of a boat) and also recognise that it's not hypochondria (dismissive) to be assertive about your chronic health conditions (the hold of the boat, with holes to patch, engine to look after, fuel to add.
