Where can I find auditions for commercial/tv/film?

I am into acting and singing. I've taken classes for both basically my entire life but I can not find auditions for ANYTHING in the tv/commercial/film industry! Anybody got tips where to find some/knows an audition open right now? P.S. I'm 13 so not every audition works for me haha. I don't expect to become famous I just enjoy doing it as a hobbie
