What a milestone!

Demi Lovato is celebrating five years of sobriety, and she reflected on the occasion in a powerful Instagram post.

"So grateful. It’s been quite the journey. So many ups and downs. So many times I wanted to relapse but sat on my hands and begged God to relieve the obsession. I'm so proud of myself but I couldn't have done it without my higher power (God), my family, friends, and everyone else who supported me. Feeling humbled and joyful today. Thank you guys for sticking by my side and believing in me," she wrote.

The songstress also shared a screenshot from her "12 Steps AA Companion — Alcoholics Anonymous" app, which showed that she has been sober for exactly 60 months, 1,827 days and 43,813 hours.

It's been quite the road to recovery for the chart topper. She did a stint in rehab in 2010 and later discovered she was bipolar, and she's been open about her struggles with mental health and addiction.

"I wish that more people can understand from a point where it's not a choice to have an addiction. And with bipolar disorder, it's a chemical imbalance, and it's something that you have to figure out, your own treatment with your own team. In order to do that, it takes time … Finally, I'm in a great place where I can say recovery is possible," she said on Today in 2015.

Bravo, girl!
