Hi Cutter, Hope you are doing well. Some of the other suggestions for grounding my C made:
having an object that you keep with you at all times that has positive associations that you can touch (eg. I use a seashell, reminds me of the calming ocean waves and also positive memories).
Also, breathing exercises where you place one hand on your heart and the other on your belly and allow yourself to breath deeply into your belly while allowing the hand on your heart to remind yourself that you love yourself.
Another that is kinda funny but can work: keep strong mints or even cough drops with you... the strong taste as well as how it makes you "feel" your breathing... tends to ground you.
The whole concept of grounding is that when we are emotionally overwhelmed our brain goes into crisis mode (fight or flight). We can't think rationally when in crisis mode.
But, when we get in touch with our senses (taste, touch, smell, sight, sound) it "wakes" up the part of our brain that helps us engage in rational thought again and that soothes our emotions.
