I’m not sure what hell is up with your T and thr way she’s managing the group dynamic. I attend a trauma group each week, and it’s really essential that everyone in the group feels safe and like they’re being treated with respect, or else it’s just not a healing space, yeah?
As for the fidget spinner issue - it strikes me that your T needs to be clear on this issue. Are people allowed to use distractions like that in the group? It’s an important question, and it’s not just a question of how you’re all managing your relationships in the group.
I’ve mentioned this in a few posts before: my T brings fidget spinners, and a whole range pf small distraction toys (like, dozens) to group. They line the tables. We’re actively encouraged to use them. To pick them up whenever we need, and quietly sit there fidgeting away. I fold paper cranes as my thing.
The purpose they serve? Is to help each of us regulate ourselves. The emotions and dissociation you deacribe? That’s why they’re there. Much like someone who carries a rock in their pocket to run their fingers over and ground themselves when they’re out in the world doing their thing. It may be that you’d find a small amount of relief if, next time you feel yourself dissociating? Try picking up something like a fidget spinner, and tuning your concentration into that for a few minutes, instead of the (often overwhelming) content being spoken about in the group. It may help, it may not. It may be the reason the other group member was using the top - to help self-regulate if she was feeling overwhelmed.
The big difference to me? Is that our group facilitator is very clear with everyone from day dot: the small toys are there to be used whenever we feel like it. And on that basis? That we’re all clear that’s what they’re there for? It’s immensely helpful. Not just in the group setting either. We each go away from group knowing that we can use this sort of tool to help self-regulate wherever we are. Which is a fantastic tool to have. And because the facilitator actively encourages it - “This is something that may help you manage your symptoms” - it makes you comfortable knowing in advance that people are going to do that, and that it’s a positive tool to help the group space feel safe, not to be simply disrespectful when someone gets bored!
But, unless the group is clear that that’s what they’re there for, and that people will be using them while others are talking? It’s uncomfortable, right? Because if you’re listening to someone respectfully, out in the real world, and you just started idly spinning a top in front of someone - it can easily be interpreted as “They’re not listening, they don’t care, they’re bored...” etc etc.
If you feel up to it? Maybe ask the facilitator to make it clear to the group. Is that what the fidget spinner is there for? Is it okay if we use those sorts of distractions during group to self-regulate? And if so? Absolutely give it try. Fidget spinners, putty, origami paper - there’s all sorts of different things with different textures, smells, movement, and everyone has something different that works for them.
