I can’t log out of my family sharing on iPhone 14

Hi, and welcome to the Apple (user-to-user) Community!

Re: "I cant log out of my family : i can’t log out of my family on iphone 14, and i am already 13"

If you have Screen Time turned on for your account, the family organizer must remove you.

Please note:

When you leave Family Sharing, you lose access to any shared purchases or services shared by the family group.

says you can:

"Remove yourself from a family group:

Any family member age 13 or older* can remove themselves from a family group.

On your iPhone or iPad

1. Open the Settings app, then tap Family. If you don't see Family, tap your name, then tap Family (or Family Sharing).
2. Tap your name, then tap Stop Using Family Sharing."

All the best :-)
