Amber Portwood HANDCUFFED -- The Final Moments of Freedom [PHOTOS]

"Teen Mom" train wreck Amber Portwood was handcuffed and taken into custody yesterday -- after asking a judge to lock her up in prison -- and TMZ has obtained photos of her final moments as a free woman.

Amber appeared emotionless on her way into an Indiana courtroom -- where she showed up for a weekly drug court hearing -- and as we reported, she threw in the towel on the entire rehab thing.

Amber told the judge she hadn't stayed clean since he sentenced her to the rehab program following her December drug arrest ... and will always be a "bad girl" -- so she'd rather just face the 5-year prison sentence the judge originally gave her.

It was shocking, but Amber left the judge with no choice -- so he remanded her into custody.
