"I've never felt more accepted, forgiven, and supported than during this period of my life.
"This is not easy," she said.

Manning has had a crazy year which saw her file a $10 million lawsuit against New York City claiming she was falsely arrested for making criminal threats against former friend and alleged stalker, Janine Heller.
She was kept in a holding cell for four hours after trying to explain her situation to police.
Manning says her arrest was voided but cops still sold the story to the media.
Heller told police that Manning sent her text messages that read: "I will kill you, b****' and 'Go f*** yourself and die".
New York City lawyers have called for the lawsuit to get thrown out.
Manning started out as a singer, in a band called Boomkat alongside brother, Kellin.
Her big break came in 2002 when she starred in the movies Crossroads, alongside Britney Spears and an unknown Zoe Saldana, as well as 8 Mile with Eminem.
She then went on to hits such as Hustle & Flow, and TV shows Sons of Anarchy and Hawaii Five-0.
