Britney Spears is keeping fans updated on her post-conservatorship life.

The "...Baby One More Time" singer, 39, revealed to her millions of followers on Instagram that she is on the "right medication" after being in a conservatorship for the last 13 years. 

"That beautiful … nice … and warm f------ fuzzy feeling when you've been waiting patiently for 13 years to be able to live your life however you choose and it's finally here !!!!" she captioned a photo of a cozy fireplace decked out with Christmas decor, including a thick strand of garland adorned with red bows, gold ornaments, bells and white lights.

"And you might be surprised cause my prayers are pretty damn powerful ESPECIALLY when you're on the right medication just a month ago !!!!" she continued. "Damn I can actually pray  …. it feels so good to just BE HERE !!!! I'M HERE … thanks to no doctor or conservatorship people … good God my friends … it's good to BE HERE and be PRESENT !!!!"

Although Spears did not reveal what kind of medication she's on, she did hint to her followers to keep an eye out for something that could come about in the next three months.

Earlier this month, Los Angeles Judge Brenda Penny officially terminated Spears' personal and estate conservatorship, just two months after Spears' father, Jamie Spears, was suspended from his role as Britney's conservator — a position he held for nearly the entirety of the 13-year conservatorship. 

"The court finds and determines that the conservatorship of the person and the estate is no longer required," Judge Penny said in court on Nov. 12. "Therefore, effective today, the conservatorship of the person and estate of Britney Jean Spears… is hereby terminated."

A source previously told PEOPLE that Britney called the day her conservatorship ended "the best day of her life."

"She was crying and laughing at the same time," the source explained. "It was hard for her to understand that it's over after so many years. She is so grateful for everyone that has helped her."
