I'm a proponent of realizing that is someone has Acute Stress Disorder (ASD), Post Truamatic Stress Disorder (PTSD), or a Dissociative Disorder (DDNOS, DESNOS, DID) you are dealing with the same action systems + dissociation. Thus the advice to discuss with DID is not out of hand, simply they have 30 push ups and sit ups to do a day, and you have 20. Their advice may prove outstanding.
The list below is of Action Systems all humans (and some animals) share, regardless of dissociation levels of said systems:
Exploring Environment (work/play/exercise)
Attachment (crying/holding/hug)
Energy (Eat/Sleep/Self care)
Social
Caretaking/parenting
Sex
The above are "Daily Life;" and in PTSD or in any Dis.Disorder, the above can be "Numb" or "avoident," as in not feeling hunger, sex, or the need for sleep cues.
Then in PTSD we have intrusions of the "Defenses:"with several subsystems:
Hypervigilance,
freeze, flight, fight, total submission (Fanselow & Lester, 1988; Misslin, 2003), and some forms of
social submission [fawn] (Gilbert, 2000).
Recuperation follows survival of attack,
Primary SD = PTSD
Secondary SD = DDNOS (which is like DID but without the amnesia between parts and elaboration of the ANP into full on personalities)
Tertiary SD = DID
Positive and Negative symptoms comingle.
Because DID can mask itself as DDNOS for years, DDNOS is often simply treated as if it were DID in disguise. The same action systems are dissociated. The major diff. between DID and DDNOS is that the ANP is more unified in DDNOS and the parts are more co-conscious. The EP's intrusions are not dissociated away, so flashbacks are mostly remembered later but can be fuzzy.
Unfortunately, when parts first start appearing in any of the above, it is upsetting because those EP's are in tremendous pain and often re-enact their pain for the same duration as it lasted the original trauma.
Once processing/understanding is underway, the time length of the parts take overs can be foreshortened by immediately realizing what is happening and taking action to ground or relieve dissociation: See Pete Walker's 13 Steps to Flashback Management: PDF:

I find that drinking ice water through a straw, as soon as I can manage it, and talking as much as I can about what is happening grounds me and brings my ANP back into play. However, I do not dimiss or shrug off the EP; rather I journal and talk with it, ask it questions, and for any additional memories it has, so that I can make the most narrative memory out of the awful experience.
I basically add its information to my timeline and trust its experience, validate it, and give it whatever it wants to calm down.
Last time, it wanted a "My Little Pony" so while I sipped my ice water and applied my Vicks (aromatherapy to cut dissociation) my spouse retrieved one of my kid's toys. I stroked it and then remembered a strong, positive memory of Chuck E Cheese with a BFF. I was expecting more trauma, but the EP actually help peritraumatic memories of positive childhood experiences that followed the trauma later. This is how you put the timeline back in order. You take all memories, good and bad, and just stick them on the timeline. :)
Good luck! It's not all painful, is the lesson. Bittersweet.
An the T's may be dumb-asses, but well-intended dumb-asses at that. No need to demonize. If their intent was to harm, then, please sue their dumb asses ASAP.
