— -- Actress Shannen Doherty continues to document her ongoing cancer battle on Facebook, sending a message of thanks yesterday to family and friends.

"Thank you to these three who helped me thru an impossibly tough day and continue to be there every minute supporting and loving me," she wrote, along with a picture of her mother and two close friends. "@kurtiswarienko was in Mexico working but knew he left me in good hands. @annemkortright @chriscortazzo ?#?mamarosa? I love you. ?#?mycrew? ?#?thisisasquad?."

This inspiring post comes a week after the former "Beverly Hills, 90210" star, 45, shared several brave pics, shaving her head in the midst of her breast cancer treatment. She labeled them steps on both Facebook and Instagram.

Doherty revealed her cancer diagnosis last summer. She also filed a lawsuit against her former business managers, who she says "blundered" her insurance payments, causing them to lapse, in court papers obtained by ABC News. A lawyer for the firm has denied this claim and the suit is still ongoing.

The Hollywood Reporter added in April that the depositions from the case and Doherty's medical records have been sealed with a protective order.
