My understanding is a bit of a hybrid between my past life brain as an RMN and my patient brains now. I am very, very quick to fall into dissociation today so sorry in advance if this doesn't flow very well!
There isn't 'trauma top trumps'. Trauma is trauma, it looks very different dependant on so many factors, but your basics like age, level of external support system, environment, physical health etc etc etc. The list of factors could be countless.
I personally really like elements of Carolyn Springs take on trauma and dissociation, how it's shaped and how it's healed, but you'll find 101 different opinions out there and I guess it's about what feels right for you.
Being able to accept trauma as what it is is no easy task...I've been trying for years and still I feel like I'm the biggest liar out there who I only a second away as being outed for failing to just cope with life like a normal person. Being one of a system this makes it harder still, as I'm trying to take on board opinions that are completely at odds from my own, but come from the same body.
If it's something you want to explore with your T, take it slowly and see where you go, just be sure that they are skilled in the areas of trauma and dissociation- many claim they are... (A three day course doesn't make you a trauma expert)
