Interesting you got that interpretation from my post that "everyone" is like this, and from that, draw the conclusion it's better to hide,...not quite what I had intended.
The OP had and is having a bad experience, as well.
On the other hand, and I have said this many times on here on different threads,...to whom you chose to disclose your autism to is highly individualized,...I was not clear with this,...my fault. However, there are many folks on this forum who have had bad experiences,...similar to mine,...the "late diagnosis" and then having it backfire on them upon "coming out" to close family, friends, and the boss at work. Having said that, sometimes it IS best to be very forthcoming,...for me,...it's my students and new employees that I am mentoring. I've never had an issue with this,...mainly because they have not the personal history with me and have formed a moral diagnosis prior. It seems that once someone you know has formed a judgement of you,...it is difficult to overcome this,...even with a professional diagnosis that lends some explanation. "Hey, guess what? You know when this happened and I reacted that way? It bothered me so much I went to the psychologist, was tested,...and I've had a form of autism that I didn't even know I had." This is my personal experience, but I have never,...never,...had anyone I knew prior to have any sense of acceptance. I've got a few to say, "OK",...nothing more,...no questions,...no "How does this make you feel?",...zero interest. My wife,...still,...it's been 3 years now,...very quiet,...never giving any indication of understanding. This is my rock, my partner of 35 years,...a highly educated person in the medical field. She hasn't said anything that would indicate denial,...she was part of the interview process with the psychologist,...but it's like, "Well,...you don't have that bad of autism." "Excuse me,...my social responsiveness was rated "severe",...but I guess all that means is that I am an introvert?" "No accounting for my sensory experience?....You'd call an ambulance...You have no sense of perspective."
Yes, there are many, many people who have an autism experience far, far worse than I do. I get it. However, do we all have to be that severely disabled child in order for an adult autistic to receive some sense of acceptance from the people in our lives? All I would like is some indication that someone I knew prior to my diagnosis has some sense of empathy and acceptance,...which I haven't seen yet.
