I've often struggled in social situations, I've had problems with friends, and I've had friends simply laugh at me "Oh my god, you're so strange some times" and just take the piss out of me and the things I do / I've done.
Sometimes it hasn't mattered, other times it's really bugged me as I've not understood why I'm the one at fault / why I'm the weird one, and why it's not them that's weird for not thinking the way I do.
Getting informally diagnosed has helped heaps, and resulted in a lot of internal turmoil being significantly subdued. I'm a lot calmer and a lot more secure in my sense of self.
I still operate with a "mask" or "game face" in a range of social situations to avoid standing out like a sore thumb, but I no longer feel the need to ply myself with masses of alcohol to drown the inner turmoil, and I no longer fear the occasional inevitable moment where I'm going to put my foot in it, as I now have an easy narrative to jokingly explain my faux pas away ("oh my gosh, I can be so aspie sometimes, sorry!").
I also no longer obsess about events to try and better understand where things have gone wrong, again caused by wondering "what's wrong with me?" as I now understand that there's nothing wrong with me, I'm just wired a bit differently.
I don't feel the need to get a formal diagnosis, as I now feel like I finally understand myself. Ultimately, life just feels better now.
