I understand your pain.
I UNDERSTAND.
I don't know what to tell you. It should be interesting to you and relevant to the times.... erm...
Personally, I'm interested in topics like psychology and sociology. Especially criminal psychology. I don't know what you like, though.
Oh wait, you write FANFICTION. You like FRERARD. Dude, write about gay rights or something. Or how homophobia is gay. Homosexuality as it is impacting our culture and society... Kinda like that. Or maybe how some websites such as this one, instead of being dangerous, brings people closer together. Or how fanfiction about bands can have positive/negative effects on the band members, or the fans.
I DON'T KNOW WHAT YOU SHOULD DO GAAAHHHHH JUST PICK ANYTHING
