yes the term ...mental health provider...here means therapists/counselors, psychologists, and psychiatrists.

I also use the term ...treatment provider...for each of those and also include all forms of medical doctors too.

yes here its treatable. there are many ways that work with people with flashbacks and intrusive thoughts...some of those ways are medications, talk therapy, grounding, yoga...and lots others.. it all depends on what works for each person.

for me what works for intrusive thoughts is medications, grounding, yoga, calming activities like boating on the lake..
