Since my diagnosis, it's kind of worked in the opposite direction to what you've described. Prior to the diagnosis I was (without equating it to being autistic) filtering everything that I said before I said it... which was very tiring... and if I got it wrong (which may or may not have been the case... the other person could have just been having a bad day), I would berate myself to such a degree that depression and anxiety would hit me like a ton of bricks.

Now however, having had some closure with the diagnosis (I'd figured there was something wrong but didn't know what), I feel a bit of security in acknowledging that I'm not always going to get it right... the other person doesn't need to know why... but I do, and I can just learn from the experience.
