When people hear about “bad habits” like biting your lips or picking at your fingers, they imagine it’s something you can simply stop. A matter of willpower. But for those of us who are neurodivergent, living with ADHD, autism, or sensory processing disorder, these aren’t habits. They’re survival strategies. They’re called stims.
What Stimming Really Is
Stimming, or self-stimulatory behavior, is a form of self-regulation. It’s the body’s way of calming an overwhelmed nervous system or maintaining focus in a chaotic world. For some people, stims are harmless, like bouncing a leg or twirling hair. But for many of us, they turn into body-focused repetitive behaviors (BFRBs), where our own skin becomes the outlet.
My Personal Reality
For me, this has meant decades of bloody fingers, shredded cuticles, and raw lips. I bite, pull, and pick until the skin breaks, often without realizing it until it hurts. Add jaw clenching and tensing around my eyes, and I end up with headaches, tension, and even worn-down teeth. It’s not pretty, and it’s not optional. Stress, sensory overload, or even deep concentration will trigger it.
I once walked around with bandages on every finger, hiding the damage from myself and others. I tried the usual “cures”: bitter nail polish, snapping elastics on my wrist, even sheer force of will. None of it worked—because the root cause was never “bad behavior.” It was my nervous system crying out for regulation.
Why Neurodivergent Brains Do This
Research into sensory processing disorder (SPD) explains why so many autistic and ADHD people stim. Our brains process stimuli differently: louder, brighter, more intense. Stimming releases that pressure. For some, it’s repetitive movement. For others, it’s skin picking, biting, or clenching. What looks destructive is actually an attempt to survive sensory and emotional overload.
Finding What Helps
My turning point came with something as small as a fidget ring. I was skeptical. After thirty years of bleeding fingers, how could a piece of jewelry fix it? But it worked. The repetitive motion my brain craved finally had a safe outlet. For the first time in decades, my lips and fingers healed.
That’s the key: not punishment, not shame, not “just stop”, but replacing harmful stims with ones that meet the same need without leaving scars. For some, that might be fidget jewelry. For others, textured fabrics, putty, or movement. It’s about trial and error, and about giving ourselves permission to stim safely.
The Bigger Picture
Stimming is often misunderstood, even within neurodivergent spaces. Not every autistic or ADHD person experiences it the same way. Some stim outwardly, others inwardly. Some destroy their skin; others don’t. The spectrum is wide. But for those who live this reality, know this: you’re not broken. You’re adapting.
Final Thoughts
Body picking and jaw clenching aren’t quirks I can laugh off, they’re part of my neurodivergent wiring. They’ve caused pain, scars, and frustration, but they’ve also taught me resilience. I’ve learned that my body isn’t the enemy. My nervous system is simply looking for balance.
If you struggle with BFRBs, you’re not weak. You don’t lack discipline. Your brain is wired differently, and that’s okay. With understanding, compassion, and the right tools, healing is possible—sometimes one fidget at a time.
