Why do we go numb?

People describe it in similar ways: functioning normally, saying the right things, and watching it all from slightly outside. Not sad exactly. Not anything exactly. Often accompanied by guilt, because from the outside nothing is wrong.

It is usually protective

Turning the volume down is something people do, mostly without deciding to, when feeling something fully would have been unmanageable at the time. After a long stretch of stress, after a loss, during a period when you had to keep functioning for someone else. It is a competent response to circumstances that did not permit falling apart.

The difficulty is that the mechanism is not selective. It does not lower only the difficult feelings; it lowers the pleasant ones too. Which is why the complaint is rarely "I can't feel sad" and usually "I can't feel much of anything, including about things I used to enjoy".

You did not stop caring. The volume went down, and the dial is not labelled.

What tends to bring it back

Not insight, generally. Understanding why you went numb does not turn the volume back up, in the same way that understanding why you are cold does not warm you. What seems to help more is contact, sensory and relational, in small amounts:

• Being outside, with attention on what you can actually sense. Temperature and sound tend to land before anything else does.
• Doing something with your hands where the outcome does not matter.
• Being with someone who does not need you to be alright. This is different from being with people.
• Music you have a history with, which often reaches things conversation cannot.

When it needs more than this

If numbness has been constant for months, if it followed something frightening or traumatic, or if it comes with not wanting to be here, that deserves proper support rather than self-management. Speaking to your doctor or a registered mental-health professional is the right step, and it is not an overreaction.
