Welcome from another UK member.
I too am in the process fo being referred. I just discovered AS a few weeks ago at 30, It is a bit of a shocker when you have been living under the assumption that you are 'normal' with the odd quirk. So so much makes sense in terms of this though and it is getting silly the sheer ammount of traits I actually match up with now that I look into it properly.
How does this make you feel? Is it a relief to know finally? I have a bit of that feeling but also this scary sense of not really knowing who I am anymore. Do you get that?
Anyway, welcome to WP
