"Intrusive and not ASD friendly"

When I go to an appointment that is literally pre-organised and all I know of is that I am going to be fitted with a piece of plastic in my mouth, that's all I expect. I don't expect to be interrogated about other problems I have struggles with. Nor am I going to sit there getting into detail about these problems whilst feeling intimidated. I have high anxiety among other things and it led to me self harming when I got home. Such horrible unnecessary bedside manner.
