How to say this in japanese native?

[littlegirl]

I was wondering how to say this in native japanese language:

my mother knows that now other people know this

(context : about her fear of earthquake)- no need to translate


and from now on, she will hide this truth

my mother also deleted her facebook profile to hide everything!

(context:no need to translate:because she don't want people worry about her and lives in a country with many earthquakes)

thanks a lot for the help!

私の母親は他の人がこれを知っていることを知っていますã€​‚
honestly, the english sentence is confusing and awkward so I would fix it.. it sounds repetitive is all
そして、私の母親はすべてを隠すためにフェースブックを消しました。
everything is ambiguous here, so make it more specific?
