The Fine Gael TD for the constituency of Dún Laoghaire has been an elected representative for 16 years.
She was de-selected from the party's election ticket last November following the swing-gate controversy.
Deputy Bailey says the past number of months have been extremely difficult.
The Fine Gael executive deselected her as a party candidate in late 2019.
It follows the swinggate controversy where she tried to sue a Dublin Hotel after falling off a swing at the property.
She said the Taoiseach has contacted her to confirm her deselection after a vote by her local branch calling for a review of the election ticket.
Deputy Bailey said she raised serious issues about the procedures of that branch meeting.
She added that she had been hoping to move on and work hard to rebuild her reputation, but that anonymous sources have been working against her at every turn.
