So, when I was diagnosed with ASD they told me mine was moderate and not mild, despite how I presented. I sort of laughed this off at the time because I felt that, while there were gaps, I was getting most things right. The thing is that was because I was missing a bunch of stuff that I was certain I was getting correct.
I am older now and have friends who tell me when I slip up and it has made me realise how little I actually know and all my confidence was on very bad foundations before. On one hand it helps me fix problems before they become serious and helps explain people's reception to me in the past, such as the fact that I didn't know you should smile at people to acknowledge them when you pass them and not just stare blankly at their face or respond with "Wait we are friends?" when someone calls you a friend (I never feel secure stating that fact in case I am wrong). On the other hand it makes conversations suddenly a lot more confusing, especially when I find that my reading is completely wrong.
For example, I accidentally said something that came out sounding sexual when that was not intended and apologised, hiding my face when I realised my mistake. I read that as an awkward situation, apparently it was just seen as amusing. I have been convinced people hate me, only to find out they were tired, sick or confused. Friendly, affectionate jokes are seen as scathing criticism. I completely miss people trying to connect/talk with me. In each case I was sure that just this once I was right in my interpretation only to find out from people there or who I explain the situation to that I was completely wrong.
I find this so embarrassing because it feels like the problem is me being arrogant enough to think I have any idea about what is happening. No one else thinks like this and people are generally very sympathetic. Do you feel the same when you make these mistakes? I think for me a lot of this comes from a lot of how I present myself is accidentally rude and I hate the idea of upsetting people, even if it is not on purpose. Thinking of people remembering me like that is painful.
