Are there any peer support groups or system she can tap into?
I can recall despising the school psych when I was younger - and others liking her - but I can also pinpoint now exactly why I despised her (yet if you asked me back then, I would not have been able to explain other than I wanted nothing to do with her) - because I felt somehow like I was singled out or "defective" in having to undergo all the testing and to me, it seemed like I had spent a lot of time testing for one thing or another outside of the usual classroom. I had the same issues with ST, and it is the same feelings. The only specialist I liked was my special ed teacher - because she introduced me to her other students in the other schools, who had the same condition and issues as me, and she made me feel like it was not a disability to be singled out or the central part of my identity as others sometimes seemed to force on me, but rather just something that she accept as a matter of fact, strong will (I was difficult to add on top of that), and her unwillingness to let that be the sole definition of who I was when I was with her.
And I wonder - is this something that your daughter is struggling with with specialists like the psych? Are there others she can meet who she can look at and realize - it is not who she is nor central to how she has to define herself, but just one facet of her world?
