For me personally, I’ve not been retraumatized but I’ve been triggered, several times. Just last week I was doing this breathing exercise over a large ball and she gently went to put her finger on chin to open my mouth a little wider and as she raised her hand I immediately lifted my hand to stop her.. it happened just like that. It’s not the first time we’ve done this breathing exercise but I still have some discomfort with touch due to earlier experiences. She is aware of this so I don’t feel too awkward about it.
