The `Skyscraper` singer - who entered rehab last November for three months to receive treatment for an eating disorder and self-harming - is thankful for the support she has received from her loved ones and tries to surround herself with people who can help her stay on the right path. She said: "I surround myself with people that are beneficial in my recovery and my recovery is still a daily battle and I definitely hang out with people that support me in making the right decisions. "I`m a happier and healthier person today because of the choices I`ve made. "Having the support of other artists and musicians and actors is really incredible and I`m thankful for that. I`m thankful to have that kind of support from people I look up to." Among those who have supported Demi is newly-married Kim Kardashian, who the 18-year-old star describes as a "big sister". She told E! News: "She`s been a friend of mine for a little bit and she`s like a big sister to me. So, when she got to announce me performing at the Do Something Awards it was really cool, and we actually got glam together."
