Still grunking but coming from the past to day diagnosed chronic (I assume she means complex which is what the C actually stands for you utter plantpot Jack) MY ARSE. It is incredibly incredibly difficult to find medical professionals in the UK who have the specialism and awareness to diagnose. Most are mistakenly diagnosed with BPD or other related personality disorders. It'd usually specialist psychiatrists that have to be consulted privately who diagnose, and more often it's after long and hard and expensive work finding a good, knowledgeable and experienced therapist where you'll become aware that it's CPTSD - and said therapists can't diagnose.
As someone with actual CPTSD who lives with the utter life altering and life destroying symptoms and repercussions of that, she can get in the bleeping bin trying to add another identity to her collection.
