Writing

Harry Potter. In my case, "obsession" is an understatement.

Fashion. Period. I go crazy over cute things; namely boots, dresses, purses, and cardigans..... and all things vintage, of course.

Writing. Related to that is books. I love reading them as well as collecting them. Nothing is more satisfying then seeing a pile of books just waiting to be read.

History! I'm a huge geek.

Drawing and art.

Grammatical and spelling errors. They drive me insane, and I'm obsessed with correcting them.

Jonathan Park series (audio)

I'm obsessed with history. I just love it!! Castles, costumes, movies, books, anything!! I do reenactment of Russia in the Middle Ages, but I love anything to do with history ranging from ancient empires to World War II.

I'm also obsessed with Jesus...He's the One I'm living for, the One who died for Me and saved me from a horrible life of depression and hate. I'm indebted to him forever - He's my passion for living.

I also really love the band "Pillar". Love their music, their attitude, their music videos, everything!!

Oh, and of course the Lord of the Rings and most fantasy...(with the exception of Harry Potter)

I am obsessed with the French musical Romeo and Juliet!!!! You can ask Narnian_Archer! I am just CRAZY over it! I watch it all the time

Doctor Who. Definitely Doctor Who.

Lord of the Rings.

Graphics making

Interior Design.

Theology.

Being Outdoors.

Nancy Drew PC Games.

ehehe I'm with you on that one

Books are one of my obsessions, I just LOVE them, I'll read anything I can get my hands on (provided it's something positive and not depressing or misleading, after all you are what you read ) I really love my bookshelf *three cheers for books*

History, I really am obsessed with history, I love to read and study it and reenact it

Cactuses, this may sound kinda weird, but yes I am obsessed with cactuses, I have a large collection of them, they are the only plants in our room, and I add to it as often as I can

Dragons, faries, mermaids, dryads and nyads, I like to think that they really do exist, they just never show themselves whe we people are around
