Kelly Osbourne is celebrating one year clean following a recent lapse with substance abuse. In a new Instagram post, Osbourne shared her recent success and how it’s been “one of the hardest years” of her life.

The daughter of Ozzy and Sharon Osbourne famously entered rehab in 2004, which was documented in Season Four of The Osbournes. Kelly has been to rehab multiple times for abusing painkillers, leading a sober life for periods of time before slipping back into old temptations.

The Fashion Police / Project Runway Junior personality thanks her family for helping her through the last year:

This past year has been one of the hardest years of my life and I feel it’s time share that with you guys. To cut a long story short things got really dark. I gave up on everything in my life but most of all I gave up on myself. Life on life’s terms became to much for me to handle. The only way I knew how to function was to self medicate and go from project to project so I never had to focus on what was really going on with me. Something had to give... and it did. I have spend the past year truly working on my mind body and soul! I had to take a step out of the public eye away from work and give myself a chance to heal and figure out who the fuck I really am without a camera in my face. I want to take this time to thank my brother @jackosbourne who answered the phone to me one year ago today and picked me up from where I had fallen yet again without judgment. He has held my hand through out this whole process. Thank you to my Mum and Dad for never giving up on me. I love my family with all my heart. Thank you to the friends who have walked the path of sobriety with me I could not have done this with out there love and support. I can’t believe It’s been a year!!! I still don’t know who the fuck I am or what the fuck I want but I can whole heartedly confess that I’m finally at peace with myself and truly starting to understand what true happiness is. I’m sorry if I let anyone down it was just time for me to work on me! I love you guys!

We’d like to congratulate Kelly Osbourne for her year of sobriety and we wish her continued health.
