Manning also faced new charges in July 2016: three administrative prison offenses related to her first two suicide attempts past year.
Manning - then known as Bradley - was convicted in 2013 for stealing 700,000 military files and diplomatic cables and giving them to WikiLeaks in 2010.
Manning struck a similarly optimistic tone in a statement Tuesday after her impending release was announced.
Manning said she would be "forever grateful" to all those who had supported her and President Obama, and now hoped to make "life better for others".
She received a commutation from President Obama in one of his final acts in office in January after an outpouring of support for Manning from the public over her mistreatment in prison and opposition to the extremely harsh sentence. Before Obama cut 28 years from her sentence, she was going to serve 35 years in a men's military prison.
A former Army intelligence analyst and transgender woman, Manning was sentenced to 35 years in prison after being convicted in 2013 of stealing 750,000 pages of documents and videos before leaking them to WikiLeaks - one of the largest and most embarrassing leaks of classified information in United States history. "I can imagine surviving and living as the person who I am and finally be in the outside world".

It will be released alongside other phones in the Moto Z lineup for 2017 and will be available in grey and gold color options. It's mostly known for having a larger battery and a headphone jack, though it's also thicker and heavier than the Moto Z.
The White House has said her sentence would end on May 17.
"For the first time, I can see a future for myself as Chelsea".
The Department of Defense has repeatedly declined to comment on Manning's treatment in prison. In prison, Manning's longstanding struggles with depression continued; she attempted suicide on several occasions, prompting authorities at Leavenworth to gig her for misconduct and place her in solitary confinement, a move her attorneys protested as cruel and unusual.
"Chelsea has already served the longest sentence of any whistleblower in the history of this country", said Hollander and Ward in a joint statement Tuesday. After being placed in solitary confinement as punishment for the first suicide attempt, Manning again tried to take her own life in October.
Her attorneys said Manning was subjected to violence in prison and argued the military mistreated her by requiring her to serve her sentence in an all-male prison, restricting her physical and mental health care, and not allowing her to wear a feminine-style haircut.
She also went on a hunger strike past year, which she ended after the military agreed to provide her with gender transition treatment.
