I figured it out:

function my_acf_validate_value( $valid, $value, $field, $input ) {
	
	$current_id = get_current_user_id();
	$wp_user_id = 'user_' . $current_id;
	$current_email = get_the_author_meta('user_email', $current_id);
			
	if($value == "" || $value == " ") {
		$valid = "Email field cannot be empty";
	} elseif( email_exists($value) && $value != $current_email ) {
		$valid = "This email already exists. Use a unique email";
	}
	return $valid;
	
}

I figured this out. I’d like this validation to only be on the front end of the site not in the admin area. I’ll start another forum thread for that.
