Guilty over really stupid things?

Hey im 12 and just going into puberty. ok please give me serious answers i am super worried and sad and angry and GUILTFUL. I am mostly guilty from seeing many suggestive pictures online. I am also feeling this way from seeing even animated suggestive content (mods for morrowind, South Park) i am really feeling bad and please no bad answers im trying to start over and dont want to discuss tjis with my parents. Please im on the verge of crying over guilt :(
