Need help to write this in japanese language? (NO GOOGLE !)?

Question:

(context: about earthquakes's fears and not show others this feeling)

"Now, my mother discovered that other people know this,
and from now on, she will hide this truth even more."

"She recently also delete her from the group!
(She was always in that group before)!"

thank you for help

Answer:

「というわけで、皆この事を知っているってことが母に判ってしまったのです。
今後は、とにかく母もこの事実をひたすら隠し通すとは思うのですが。」


「更に、母は最近になってそのグループから離れてしまったんです！withdre… herself from
（以前はずっとそのグループと関わっていたのです。）」

*Without knowing "this feeling", "this truth", I cannot get inspired to write good Japanese...
