Lindsay Lohan is grateful to rehab

Lindsay Lohan is thankful she went to rehab because now she has a "clear" head.

The Mean Girls star entered a rehabilitation facility three times last year (2007); in January "to take care" of her health, again in May after she was accused of driving under the influence (DUI), and finally in August to confront her drink and drug problems.

She finally left rehab in October 2007 and has since turned her life around.

Lohan says she is a different person now and very happy.

The actress admits feeling lonely before her stints in therapy.

But Lohan has taken responsibility for her downward spiral and is ready to move forward. Lohan blames herself for her consequences but now she is absolutely fine. (SAMPURN)
