Selena Gomez ''lost sight'' of who she was before she checked into rehab in January.
The 21-year-old singer secretly spent two weeks at Dawn at the Meadows treatment facility in Arizona, and she's admitted she listened too much to other people in the hope of fitting in.
During a heart-warming eight-minute speech at the We Day California event in Oakland yesterday (26.03.14), she said: ''You all have pressure that you have to deal with every day - with school, with work, with friends, with parents, with family. They tell me what to wear, how to look, what I should say, how I should be.
''Until recently I had given into that pressure, I lost sight of who I was. I listened to opinions of people and I tried to change who I am because I thought others would accept me for it. And I realised I don't know how to be anything but myself.''
The 'Come & Get It' hitmaker, who has been in an on/off relationship with Justin Bieber for three years, also encouraged the youngsters at the event to chase after their dreams.
She said: ''I'm sure all of you have been told that you don't have what it takes and that you may not be good enough... when deep down, it's all you want to do, you want to be part of something great, you want to make something great.
''It crushes you when people try to tell you that you're not good enough.''
