I was publicly humiliated on a website, can I take legal action?

I have requested the website owner who basically told me too bad due to the fact he didn't post. The website in 2012 reported to have a traffic of 22 million in one day. The posts were stating I have had sexually transmitted diseases, statements about me claiming I have a sister that was murdered when I do not even have a sister, countless claims of me having affairs with different men, and having videos of myself performing sexual acts floating around the web. None of these which is true along with horrible hateful comments about my appearance and where I work, he removed one comment that said the address of where I had worked though. I would like to sue for defamation and cyber bullying as this has gotten to the point where it is taking a toll on my day to day life with people constantly asking me about it or bringing it to my attention, it's humiliating.
