Time alone isn’t hiding if you walk out of it a little clearer than you walked in.

The difference between withdrawing and restoring is not how long you were alone but what condition you come out in. If a few hours by yourself leaves you steadier and more able to be around people, that was maintenance. If it leaves you further away each time, something else is going on and it deserves a gentle look.

Use the exit as your measure rather than the guilt. Ask how you feel walking back into the world compared with how you felt going in. That single check will tell you what you need to know without any need to justify the time.
