I don't tell many people, because of some bad experiences I have had telling people. Especially my mother. For most of my childhood, my mother was constantly telling me to "just be normal", and when I had some trouble with ways I was different, she would say "everybody is a little different, you are not the only one". She would also say that I should "stop acting like my father". They were divorced when I was young, on bad terms, and my dad's side of the family has had a history of autism. Many people I know on that side of the family have autistic traits.
So, you can imagine my mom's reaction when I told her I had been diagnosed with autism. I only brought it up once. The same has gone for some acquaintances that used to be friends, as well as my sister. The response that I have gotten is that I basically need to just grow up or get ahold of myself and stop acting this way. That I am just being stubborn by not being like everyone else.
Do they think that the many years of depression and self-destructive behavior I went through were something I could just snap my fingers and turn off? They didn't feel the anguish and alienation of growing up in an environment where there were strict expectations to behave, think, and even FEEL a certain way, a way that wasn't the least bit natural. I seriously doubt they ever will understand. Hence, I am building a life of my own, on my own. It's lonely, hard, yet worth it.
So, yeah, I am reluctant to tell people.
