How can 20 minutes fly by when you’re catching up with a friend, but feel incredibly slow if you’re waiting in line? It all comes down to perception. The seconds measured by a clock and the time felt in someone’s body are often completely different. In the rare condition known as tachysensia, a person experiences a temporary distortion of time and sound, during which they get the “fast feeling” that everything is moving more rapidly than it actually is.
Why Tachysensia Makes Boundaries Harder
Setting and maintaining boundaries is challenging even without mental health struggles. Tachysensia adds specific layers of difficulty:
- Fear of rejection or abandonment makes saying no feel existentially threatening
- People-pleasing patterns developed as coping mechanisms
- Difficulty recognizing your own needs when tachysensia clouds self-awareness
- Guilt and shame about having needs or limits at all
- Fatigue from tachysensia reduces capacity to enforce boundaries consistently
What Healthy Boundaries Look Like
Boundaries are not walls or punishments — they are guidelines about what you need to function and feel safe.
Types of boundaries affected by Tachysensia:
- Energy boundaries: Limiting draining interactions or commitments
- Time boundaries: Protecting rest and recovery time
- Emotional boundaries: Not taking responsibility for others' emotions
- Physical boundaries: Space and physical contact preferences
- Digital boundaries: Response times and availability expectations
Setting Boundaries When You Have Tachysensia
Start Small
Choose one low-stakes boundary to practice. Success builds confidence for harder ones.
Scripts for Common Situations
- "I care about you, and I need some time to recharge. Let's connect on [specific time]."
- "I'm not able to take that on right now, but here's what I can do..."
- "I need to end this conversation now, but I'd like to continue another time."
Handling Pushback
People who benefit from your lack of boundaries will resist when you establish them. This resistance is not evidence you're wrong — it's evidence the boundary is needed.
When Tachysensia Makes Boundaries Feel Impossible
If tachysensia has severely compromised your ability to recognize or assert your needs, therapy — especially dialectical behavior therapy (DBT) or attachment-based approaches — can be transformative.
