Passions & Obsessions

I've been thinking about my theme for a couple of days now. At first I wanted to do my own passion and thought about themes like books and collecting certain objects but it hasn't inspired me at all. I've decided I'm going to do a common obsession. Either obsession with a certain person (love), stalking or dugs and alcohol. I'm still not a 100% sure about my theme but it's going to be a common obsession.
