I'm also having a hard time understanding, but maybe you meant (summarized): I met/saw the person I like at otakkumekkusu but they don't like me, love is dead.
But actually in Japanese you wrote that you saw the person you like but YOU don't like them. lol
As inosan suggests, if you include the english version we can know which parts are the mistake and which are correct.
Sorry. I can't understand what you want to write.
You might want to write in English and Japanese.
