I have my special interests that I've had most of my life and some that are just a period of time. But sometimes I get obsessed with doing small things, I just have to do them. For example, I recently ordered a christmas gift for my son online. Once I decided to get it, I spent hours and hours finding the right thing, checking out different stores and comparing prices. It feels like when I'm occupied with a special interest, lots of time goes by without me noticing it, I get super focused. That's all I can think about and I just have to do it, I would get really annoyed if someone interrupted me. It also happens with other seemingly small things, once I set my mind to do something it just have to happen. Sometimes I also do things without thinking about consequences, just because I've already decided to do it.
I was wondering if this is something you can relate to, is it an autism thing? I've only heard of this kind of super focus when it comes to special interest, not with other small, daily things. I just got my autism-diagnosis a few months ago, so I'm still trying to figure things out. And this seems like the right place to ask, with so many nice people.
