The 65-year-old actress previously said she quit Twitter after she received backlash for a racist tweet she wrote Monday night about former Barack Obama advisor Valerie Jarrett. But late Tuesday night the star went on yet another Twitter spree, blaming her racist Tweet on using the prescription insomia drug Ambien.

“Don’t feel sorry for me, guys!!-I just want to apologize to the hundreds of people,and wonderful writers (all liberal) and talented actors who lost their jobs on my show due to my stupid tweet,” Barr tweeted. “I will be on Joe Rogan’s podcast friday.”

“Guys I did something unforgiveable so do not defend me. It was 2 in the morning and I was ambien tweeting-it was memorial day too-i went 2 far & do not want it defended-it was egregious Indefensible [sic]. I made a mistake I wish I hadn’t but…don’t defend it please,” she also tweeted.

Barr also retweeted plenty of her supporters with a vengeance, many of who defended her.

She added, “hey guys, don’t defend me, it’s sweet of you 2 try, but…losing my show is 0 compared 2 being labelled [sic] a racist over one tweet-that I regret even more.”

In a now-deleted tweet, Barr also wrote an apology to Jarrett, writing, “@ValerieJarrett I want to apologize to you. I am very sorry to have hurt you. I hope you can accept this sincere apology!”

The actress also claimed she was “ambien tweeting” on Monday when she made the attack on Jarrett, tweeting, “guys I did something unforgiveable [sic] so do not defend me.”

“It was 2 in the morning and I was ambien-tweeting-it was memorial day too-i went 2 far & do not want it defended-it was egregious Indefensible,” she wrote. “I made a mistake I wish I hadn’t but… don’t defend it please. ty.”

Barr retweeted a follower who wrote, “I’m calling on @ABCNetwork @Disney to uphold their “standards” by firing @JoyVBehar for calling Christians mentally ill. You can’t treat @therealroseanne one way because she supports @realDonaldTrump & allow Joy Behar to remain employed. #BoycottABC #StandWithRoseanne #Roseanne.”

Barr tweeted, “Please don’t start all of that boycott abc stuff-I’m not a censor and they have the right to do what they wish. It’ all ok. thanks tho guys!”

A rep for ABC did not immediately respond to PEOPLE’s request for comment.
