Lindsay Lohan is making "remarkable progress at Betty Ford", but her treatment team is now turning their attention on an issue that has yet to be made public.
While her substance abuse problems and history of family-related strife have often made headlines, RadarOnline.com has learned that the Mean Girls star, 24, is also struggling with anxiety associated with the continued fallout from her infamous 2007 DUI arrest.
On the night of her arrest in Santa Monica, Lohan allegedly chased Michelle Peck - the mother of her former assistant - and Tracie Rice - Peck's passenger.
Lohan also had three male passengers in her car who, along with Rice, are suing the actress for assault and negligence among other claims.
There is a status conference for the case next month, and a source with knowledge of the situation told RadarOnline.com that while the "case will be likely going to trial next April," it is currently "causing Lindsay a great deal of anxiety".
The source said, "Lindsay is taking responsibility for her actions, but this group of people just won't be happy until they can drag Lindsay's name through the mud. Lindsay's legal team has made reasonable settlement offers, but those have been rejected."
Lindsay's Betty Ford team "working with Lindsay to specifically deal with the anxiety, and the stress she is feeling about this. Lindsay and her doctors don't want this to have a negative impact on her sobriety. If this was anyone else besides Lindsay Lohan, this lawsuit never would have been filed," the source added.
Financial constraints also have LiLo concerned.
The source revealed: "The fact is Lindsay has no money. The amount of money they are seeking is outrageous. Lindsay could be on the hook for punitive damages, and that is causing her even more concern. Lindsay is scheduled to begin filming Inferno early next year and she will show up to court to when the trial begins. Lindsay will do what is asked of her," the source added.
