"And no I'm not gonna put on heavy makeup and try try try on stage again and not be able to do the real deal with remixes of my songs for years and begging to put my new music in my show for MY fans ... so I quit !!!!"
The 39-year-old star then slammed her younger sister, Jamie Lynn Spears, for her involvement in the 2017 Radio Disney Music Awards, where she made a surprise appearance in a tribute section and sang Britney's track Till The World End'.
She fumed: "I don't like that my sister showed up at an awards show and performed MY SONGS to remixes !!!!! My so-called support system hurt me deeply !!!!"
Britney and her conservatorship have recently been the subject of a number of documentaries and she admitted she doesn't like the way they have shone a spotlight on "humiliating" events in her past.
She continued: "This conservatorship killed my dreams ... so all I have is hope and hope is the only thing in this world that is very hard to kill ... yet people still try !!!! I didn't like the way the documentaries bring up humiliating moments from the past ... I'm way past all that and have been for a long time !!!! And for women who say it's weird the way I still have hope for fairy tales ... go f*** yourself !!!!!
"As I said ... hope is all I have right now ... you're lucky I post anything at all ... if you don't like what you see, unfollow me !!! People try to kill hope because hope is one of the most vulnerable and fragile things there is !!!! I'm gonna go read a mother f****** fairy tale now !!!!
"Psss if you don't want to see my precious ass dancing in my living room or it's not up to your standards ... go read a f---ing book!!!!!"
Since condemning her conservatorship as "abusive" during a hearing last month, Britney has seen her estate co-conservator Bessemer Trust, manager Larry Rudolph, and court-appointed attorney Sam Ingham III resign from their positions.
This week, the Circus singer was given permission to hire Mathew Rosengart as her new lawyer and during the hearing, she told the judge she wanted to pursue charges against her dad for "conservatorship abuse".
