1. The first step is admitting that you have a problem...that you are addicted to Seishi and you have no control over this.
2. We come to believe that there is a higher power that produced these seishi that are so addictive. Further, we believe that the higher power is pretty darn sexy itself.
3. Make a decision to turn yourself over to the deity that created your beloved seishi. Slobber over them; it can't hurt.
4. Make a searching and fearless inventory of your feelings. Make the tough decisions...are you really addicted to Tamahome and Tasuki, or are you just saying that about Tamahome? Can you really not live your life without your seishi of choice? Are you really an addict, or just another psychotic, obsessed fan? Is there a difference?
5. Tell the world very vocally exactly how obsessed you are with your seishi. It's even better if you put it on a web site.
6. Be entirely ready for the God of your seishi to bring one of them to life for you. RIGHT NOW.
7. Humbly ask your family and friends not to kill you for your constant obsessing.
8. Make a list of all the people like you instead. Go find them, and have a nice drooling conversation about your seishi.
9. Cooperate with the people like you to write fanfics about the seishi, especially self insertion fics where you...get...the seishi.
10. Continue to make a personal inventory, and when you discover there is another seishi you want, admit it promptly.
11. Seek through prayer and meditation to improve your conscious contact with the God of your seishi, praying that they will be brought to life in front of you. RIGHT NOW. Or that you'll at least meet a human being that's the exact clone of your seishi. RIGHT NOW.
12. Having become even more obsessed with your seishi, go try to convert all those non-anime watchers out there to seishi addiction.
What, you mean 12 step programs are supposed to OVERCOME addiction? Why would you want to overcome seishi addiction, anyway?
