Matthew Perry sparked concern over his well-being by tweeting that he “got kicked out of therapy” on Wednesday.

Perry, 49, did not expand further or offer any explanation. A rep for Perry did not immediately return PEOPLE’s request for comment.

Fans on social media quickly expressed their concern and lent support to the actor.

“I don’t know what is going on, but I hope you are alright and have people to support you,” wrote one Twitter user.

“Hope you’re doing good!” another tweeted. “Lots of love.”

The former Friends actor has been open about substance abuse battles, including alcohol and Vicodin addiction, throughout his life.

In August, Perry suffered a gastrointestinal perforation that left him bedridden for three months.

“Matthew was very sick when he was hospitalized; his condition was very serious,” a source told PEOPLE at the time. “A gastrointestinal surgery is very complex, and the healing can be complicated.”

According to healthline.com, a gastrointestinal perforation “occurs when a hole forms all the way through the stomach, large bowel, or small intestine. It can be due to a number of different diseases, including appendicitis and diverticulitis. It can also be the result of trauma, such as a knife wound or gunshot wound.”

Perry addressed his condition on Sept. 14 in a tweet: “Three months in a hospital bed. Check.”

Later that month, a source told PEOPLE that the actor was home and focusing on his recovery.

“He’s good,” the source said.
