get_user_meta with an array of data

I have done three functions to add, delete and update user meta.
For example to delete some user data first I have to delete user_meta stored and save it again, otherwise I get arrays inside of arrays …
Also I have to use some strange code as $user_meta[0] to get user meta correctly.
My question is: This is is the way to do it? Because it seems to work, but is very ugly code for me.

// function delete

$user_meta_backup = array();
$user_meta = get_user_meta( $user_id, 'my_data', false );
$user_meta = $user_meta[0]; // why ???
foreach( $user_meta as $key => $value)
            { if ($key != $user_id ) 
                $user_meta_backup[ $key] = $value;
            }
$delete = delete_user_meta( $user_id, 'my_data', false );         
$result = add_user_meta( $user_id, 'my_data', $user_meta_backup);  

// function add meta

$user_data = get_user_meta( $user_id, 'my_data', true);</strong>
if ( !is_array( $user_data))
    $user_data = array();
    $user_data[$user_id] = [ 'user_id'=>$user_id, 'user_name' => $user_name, 'user_email' => $user_email];
$result = update_user_meta( $user_id, 'my_data', $user_data); 

// function list user meta

$user_meta = get_user_meta( $user_id, 'my_data' );
$user_meta = $user_meta[0]; // why ???
// then list here ...
