How can I control my obsession?

[Darci]

I'm 15 and I have Asperger's Syndrome and I'm high functioning.
One of the things with me is that I become obsessed with people. I've been obsessed with SO many people in my life, from celebrities to people I know. I'll be so interested in them and I'll love them so much and the obsession will start. Like constantly thinking about them etc. I've never been obsessed with a guy, it's just women. Like not in a romantic way, not at all.
But right now I find myself being obsessed with Lee and it's driving me crazy. I message her SO much like on Facebook and text and now I'm so worried that I bug her. I've been thinking about her 24/7 and I love her so much!! She is absolutely amazing but I need help!! What do I do to get her out of my head? What do I do when I feel like I have to message her?? How can I quit obsessing over her?!?
Please help!!!!
