Catelynn Lowell is on the mend!

The Teen Mom OG star took to Twitter Tuesday to share an update with her fans after she entered a treatment facility for mental health issues last month.

“Just wanted to know I’m doing great! Best decision I have ever made for myself,” she wrote. “I’ll [be] home soon #thankyouforyoursupport.”

Lowell, 24, checked into a treatment facility March 16, telling MTV News at the time that her treatment will focus on mental health issues and not drug use.

“I’m seeking help for myself and my family,” she said. “Thank you to all of my supporters. My family and I would appreciate some privacy at this time.”

She also posted about the news on Instagram at the time, writing: “Arizona here I come… I can’t wait to be back to my normal self… this is for me and my family.. Novalee and Tyler I love you both very much!!!”

Her husband Tyler Baltierra, 24, was supportive of his wife on Twitter.

“We love ya too Amb…its just hard to see her go through all this & be away from her for so long,” he wrote.

The MTV star, who’s mom to 15-month-old daughter Novalee with Baltierra, was open about battling postpartum depression on the most recent season of the reality show. The couple also made the difficult decision to place their firstborn, Carly, up for adoption in 2010.
