Chelsea Manning, the ex-soldier whose prison term for sharing secret material with Wikileaks was commuted by former President Barack Obama, was confirmed safe on Monday after a series of suicidal-sounding tweets that reportedly showed the U.S. Senate candidate standing on a window ledge.

"I'm sorry - I tried -- I'm sorry I let you all down," Manning wrote on her personal Twitter account on Sunday, according to the Associated Press. "I'm not really cut out for this world -- I tried adapting to this world out here but I failed you -- I couldn't do this anymore -- I can take people I don't know hating me but not my own friends," she added. "I tried, and I'm sorry about my failure."

Manning, 30, reportedly removed the posts minutes after publishing them. She needs "space to heal," Kelly Wright, her communications director, told The Associated Press on Monday.

“I have seen firsthand and up close the violence inflicted on her by years of imprisonment, solitary confinement and torture,” Wright told the Associated Press. “This is made worse by the impossibly high expectations our society sets for public figures, especially on social media.”

Manning, a convicted leaker who is looking to unseat a Maryland Democrat, will not be suspending her campaign, according to the AP.
