I recently found out that the word for what I've done since before I can remember is "stimming". I flap my hands when I'm excited or thinking very hard. Because I was teased a lot in elementary school for doing it, I learned how to do it only when I'm alone.
After I found out what it was called I started reading about autism spectrum disorders, and while I'm not sure where (or if) I fall on it, everything I read about it just clicks and explains so many things about me that I thought were just me being weird and/or unreasonable.
I am very sensitive to bright lights and loud noises, to the point that my family and boyfriend get exasperated with me when I ask for the lights/TV volume to be turned down/off. It's led to me pretty much just staying in my room all day, since the loud TV is just too much for me and it just feels like a constant stress every time I'm around it or bright lights.
I was always a very socially awkward child and I still don't really know how to interact with people. I hate meeting new people or going to social events. I usually end up following one person around because I don't know what else to do. I've kind of given myself a 'routine' on how to interact with new people, but it's still very stressful and if it deviates at all I get flustered.
Changes in plans or my surroundings upsets me. I'm just beside myself is someone's told me that something is going to happen at a certain time or they'll do something and it doesn't happen. Or if I have to do something different during school/on my way to or from school it stresses me a lot, even if it's something simple like stopping at the gas station.
Sorry for the long post, I don't really have anyone to talk about this with and I just needed to get all that off my chest.
