Ke$ha -- Eating Disorder Survivor

Ke$ha wants everyone to know ... she's still standing after her stint in rehab for her eating disorder.

The singer looks good after her 60 days of intensive therapy.

Ke$ha arrived at LAX and certainly looked happy. She says she's working on music again and feels great.

Ke$ha originally was supposed to spend 30 days in rehab, but she stayed twice as long ... on her own accord.

Prior to entering the facility , she had dumped a ton of weight and looked painfully thin.

Congrats.
