Demi Lovato is shining brighter than ever following treatment for her issues.

The 18-year-old checked into rehab for some issues she was battling — mostly anger — after she got into an altercation with backup dancer Alex Welch last year.

A source close to Demi says she’s focused on keeping herself new and improved. The source told PEOPLE:

“She will continue to see doctors in L.A. who will help her work on the issues she confronted in treatment,”

“For now, she is getting back to her regular routine and spending time with her family and close friends. She is so grateful to all of her fans for their support, and looks forward to being able to talk to all of them very soon.”

“Demi will continue to focus first and foremost on her well-being.”

That’s great news! She’s still young enough to tackle inner issues and she did it successfully, so that can never be a bad thing.

Demi herself took to Facebook earlier this month to thank those who stuck by her during these hard times.

She said:

“I want to make sure my fans know how thankful I am for all their love, support and prayers during this difficult time,”

“Thank you for standing beside me through it all.”

We’re rooting for you, Demi! Keep up the good work!
