Sorry to be that guy, but IME the fidgety & anxious feeling is almost always some need in one’s life that is being unmet. If you sit with that feeling it often becomes clear exactly what the source is.
YMMV especially if you’ve experienced some serious trauma.
If you’re interested in doing this, but find it hard to sit it the feelings, consider trying Dialectical Behavior Therapy (DBT), which involves investigating the root of your feelings within your mind.
It’s best to do DBT with a professional, but there’s a large community of DIY DBT practitioners out there. [1]
If your unable to investigate the source of some feelings (e.g. because your brain shuts down when you interrogate them) there is a new-ish practice for detangling your thoughts without all the interpersonal unpleasantness of Talk Therapy (that doesn’t mean it won’t be unpleasant in it’s own way).
It’s called Eye Movement Desensitization and Reprocessing (EMDR). Again, working with a professional is best, but it’s possible to be successful with a DIY approach. [2]
Disclaimer: I’m not a professional in any form of health, mental or otherwise. I’m just a happy self-administered DBT & EMDR patient :)
Nice glad that works for you. My language was vague because the unease can come from a lot of different things. Needing exercise or food, being mad about something that happened, processing loss (of family or a job), wanting to connect or reconnect with someone, having ideas for a project I’d like to get going on are a few examples of things that have cone up for me.
In my experience, sitting with the feelings pretty reliably leads to panic spiraling. I just don't think my brain is as capable of pulling back a level as yours seems to be. And I'm not sure how to change that.
You have to keep going. You must endure and let your brain process, and learn to relax and exist in a non-stimulated state. Facebook and Tik-tok have fried our brains so much that sitting in silence for 30 minutes is painful because we are used to constant dopamine.
Try going on walks, doing guided meditations, leaving your phone in another room and reading a book for 30 minutes. You'll find your brain slowly relax, think more creatively and in a more coherent fashion. It's painful at first, but it's the most important thing you can do.
Not an endorsement, but you could look into Acceptance and Commitment Therapy (ACT). Similar to CBT but a lot of it centers around learning to notice and accept negative feelings without spiraling. Rather than trying to avoid the thoughts, it’s about accepting them and still taking positive _action_ regardless.
FWIW I am diagnosed ADHD (from childhood) and the whole thing that got me to start sitting with the fidgety feeling is the calmness that came out of the first time I sat for 10 minutes felt identical to the effect of stimulant medications for treating my symptoms.
YMMV especially if you’ve experienced some serious trauma.
