Hey Rose, idk--if we have a bad feeling come up out of nowhere, we do grounding stuff. We actually have a list of what we can do, so any one of can read it. It's mostly stuff we can do at home, like hug a big stuffed bear, get under the weighted blanket...wait I gotta look at it...ok--there's also go for a walk, work in the yard, hug the husband, hold the dog, smell essential oils (that one you could do anywhere), and text or email the T.
But I remember one time we got really triggered when we left one activity to walk to another, in the city, and for that we did the "notice 3 things you see and 3 things about each one, 3 things you hear and 3 things about each one, and 3 things you feel and 3 things about each one." I think we took deep breaths also. The 4-7-8 breathing helps us--inhale for 4, hold for 7, exhale for 8. After 10 of those we usually feel calmer.
But we're not triggered "all the time." Does your T help you with grounding stuff? Like sit and breathe with you and stuff? Ours would do that if we let him. He isn't pushing you to talk about difficult things, is he?
Oh, there's also holding one hand with the other, or hugging yourself. Medication can help temporarily, but it isn't going to teach you how to regulate your feelings. Idk--that's all we got.
