One thing I've been trying to deal with is the subconscious fear of being teased or otherwise made fun of for some of my special interests.
I'm trying to tell myself 'It doesn't matter if people make fun of me or don't understand my interests, they're my interests. I'm allowed to be myself', but it's obviously going to take some time considering I've spent nearly my entire life suppressing and hiding a lot of my interests over fears that I'd be seen as 'weird' and 'different' from the others, much in the same way I suppressed and hid all my autistic traits.
This mostly has to do with my special interests in 80s technology and 80s fashion. It's never happened, but I sometimes find myself worrying that people will make fun of me for being so into such 'old and outdated tech' or for being into the fashion of a decade I never experienced, especially so if they find out that I want to incorporate 80s fashions into my own wardrobe. It's not like I'm embarrassed by or wish I didn't have these interests, but I need to work on ignoring these worries and fears and embrace my interests wholeheartedly, as opposed to thinking myself as being 'weird' for having them.
Other than 80s tech and fashion, I'm also very into trains and rail transport too. I know that's like the stereotypical autistic interest, but I've always been obsessed with trains since I was a little kid. Thomas & Friends was my favorite TV show as a kid, I loved checking out books about trains from the library, watching documentaries about trains, etc. All stuff I still love to doing today (yes, this includes watching Thomas & Friends) and I want to ride the train as much as I can (I've only taken the train twice in my life sadly).
Other special interests I have (which I don't feel like expanding on too much because I don't want to make this post longer than it already is) are retrogaming, 90s technology (it's not as intense of a special interest as my special interest in 80s tech, but it's still intense enough for me to consider it to be one - I mean I have a late 90s gaming PC after all), magical girl anime and manga, tokusatsu (Japanese special effects TV shows and movies, although I also include Power Rangers under this umbrella), and Transformers.
