Hi Lablover,
Can I ask how old you are, dear one?
The reason I ask is because age sometimes can be a great barometer in the "way of things". The older we get and the more time that passes, the better we become in equipping ourselves for the world. In other words, we get more skills. I was not dx with AS until the age of 36, so my life has been a kaleidoscope of goodness knows what, and my parents have looked upon my life with distress and fear but the trust that I would find my way through it. The last thing I ever thought, was that it was autism.
I did not expect my parents to accept the AS dx, but strangely they did. So, give them some time to adjust, and just as I think with my parents that it is not their stuff to deal with, maybe that is how you should think with your parents. Either they will accept it or they won't, but do not lose yourself in the process. It is your journey, not theirs. You are loved.
Take good care of your precious self
Michah
