How can I deactivate my Apple ID?

You can't deactivate it as such. If you want to not use it for a while, just sign out on all your devices and then don't use it. If you believe it's been compromised, see:

If you think your Apple Account has been compromised - Apple Support

If you want to actually delete your account, see:

How to delete your Apple Account - Apple Support

Be sure you read all of the information in that article before you proceed.
