Demi Lovato thought about quitting the entertainment business following her stint in rehab

But after completing three months as an inpatient at a facility in Illinois, Demi admits she considered turning her back on the industry for good.

She said: I thought: Im exhausted, people dont understand and so many people are being negative towards me. Its hard.

There are so many pressures that are put on to you when youre in this industry. But I love doing it, I love singing, I dont want to give that up just because the going gets tough.

She has since bounced back with new album Unbroken and a new heart tattoo on her wrist.

Explaining its significance to Metro, she said: My fans used to draw [hearts] on their wrists every day that I was in treatment. I thought what better way to say thank you than to get one tattooed on my wrist.

It was incredible to have that support and I wouldnt be in the position Im in today without them. I look at my wrists every day and Im very thankful to my fans.

Demi is also thankful that her own plight has encouraged other teenagers to seek help for their problems.

She added: Theyve said Im an inspiration for helping them deal with their issues, whether thats eating disorders or cutting themselves. I didnt expect that to happen. I just wanted to be a singer. Its taken me on a more meaningful journey.
