Lizzie Sider is only 15 years old, but the country singer is already lending her emerging fame to a good cause.

Sider is fighting against bullying in schools on her Nobody Has The Power to Ruin Your Day Tour. The Florida native originally took the tour to school assemblies around her home state and in California, and now she is set to attend assemblies at 70 schools throughout Texas.

"Bullying doesn't just happen in October during Bullying Prevention Awareness Month, it happens all year," Sider told The Boot earlier this year. "As someone who understands what it is like to be bullied, I am on a mission to help anyone who doesn't think anyone will listen."

Sider uses the assemblies to share her personal connection with bullying and to perform 'Butterfly,' which she co-wrote about her experience overcoming teasing.

The Texas tour will begin on April 9 in Houston and go through May 29 in San Angelo. At the end of the tour, Sider will have visited 250 schools in the 2013-2014 school year to spread her anti-bullying message. More info on the tour, as well as specific dates, can be found on her website.
