I have plenty of short-term special interests, too many to list. he main special interest from my childhood, which continues in a subdued manner today, is vampires. Fiction, folklore, whatever.
This was a problem.
I was not diagnosed with AS until I was 24. But I had the joy of starting meds and 'therapy' at ten. The vampire obsession was considered an obsession with death, and an indicator of how crazy I am.
I really, really grew to hate that this was a special interest of mine. I learned to suppress it, but it usually comes back eventually.
Now that Twilight is a Thing?
I really, really hate that this trash disguised as vamp fiction is mucking up my special interest and causing people to think I like to read crap books.
I mostly keep the vampire obsession to myself for the above two reasons. Mostly because of Twilight these days, though. Blech.
