Feeling OK? Concerns Grow Over Chelsea Manning After She Deletes Bizarre Tweets

Friends and family grew concerned over activist Chelsea Manning this weekend.

And now they are supporting the 30-year-old after she issued and deleted some odd Tweets on Sunday.

'Chelsea is safe. She is on the phone with friends, thanks everyone for your concern and please give her some space,' her official Twitter read today.

Manning, who is seeking the Democratic nomination for US Senate in Maryland, posted some worrying messages late on Sunday.

The first tweet read: "Im sorry - i tried - im sorry i let you all down - im 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 dont know hating me but not my own friends - i tried and im sorry about my failure".

The second tweet simply said 'im sorry' and shows a picture looking down onto a street from the rooftop of a building several stories high.

The legs of a person are seen in the photo, wearing pink pajamas and with red-painted toenails standing inches from the edge of the roof.

The disturbing messages came in response to an online debate with Dawn Ennis, a writer and former ABC News assignment editor who, like Manning, is transgender.

Ennis posted a critical message that Manning wrote on May 23, which said 'voting wont change anything' and called for something 'radically different'.

Manning had expressed frustration over her US Senate bid in recent times. The activist was last seen publicly at a conference in Milan, Italy, on Sunday.

Manning is a former Army soldier who was convicted by court-martial in 2013 of violating the Espionage Act for leaking hundreds of thousands of sensitive military and diplomatic documents to the WikiLeaks website.

Former President Barack Obama commuted the sentence for that conviction and Manning was freed from prison in May of last year.
