How have things gone if you have disclosed you have (or think you have) Autism to anyone?
So far I have not told anyone 'In Real Life', I will probably wait until after diagnosis before I seriously consider it.
But I can sort of imagine some various outcomes ahead of actually doing this for real. In an ideal world, people would understand and make allowances for any difficulties. Obviously though we don't live in an ideal world, so I can imagine any such disclosures having an opposite effect to the desired one, so that instead of understanding and acceptance, a disclosure could lead to fear, and even being treated as even more weird, and being ostracised even further. I have also heard of disclosures leading people to be dismissed from work a few weeks afterwards. For ostensibly different reasons, because discrimination is illegal.
It's clearly going to depend who you tell.If you are lucky enough to have understanding close family and friends, a disclosure will probably only bring you closer. Not everyone has such good relationships though.
