A source said: "Lindsay just doesn't want to be there. She was forced to go to Betty Ford by the judge instead of going to jail. The actress looks extremely haggard, her face is bloated, and it doesn't look like she has brushed her hair in days."

"She looks very disheveled and has absolutely no energy since docs took away the Adderall," the source added.

It is said Lindsay has to accept the rehabilitation process to benefit from it.

The source said: "Until she surrenders to the recovery process, she will never have a shot of sobriety. To Lindsay, rehab is just a revolving door, and she is just going through the motions, pro forma."
