I hear my name...
Nice to "see" you again!
It is allowed to make one substitution in the FSIQ (such as SS for Cd), but only when there is reason to believe the standard subtest is a flawed measurement in some way. In any case, making that substitution here would not result in the outcome for which you hope.
I didn't check every Index score, but generally they appear to be in the right ranges, so I don't see any specific reason to doubt the accuracy of this administration. (Of course, you are reporting some emotional/mental health reasons that we might not have seen optimal performance.) It may be that these are underestimates of her ability, but documentation of that will probably need to be secondary to working on her mental health.
Your DC's results are very strong (uniformly so, by and large), with a bit of additional personal strength in fluid reasoning, and no particular patterns of weakness that stand out. It does look like she's a bit more comfortable with verbal knowledge (Voc, Inf) than verbal reasoning (Sim, Comp), but the reverse with nonverbal, with slightly stronger abstract nonverbal skills than concrete (visual spatial) nonverbal skills.
I also suspect that she may do better when working out details starting from a pattern or concept (whole to part--MR and FW are the relevant subtests), than when naming the concept, or making connections, out of bits and pieces (part to whole--Si and PC are the relevant subtests). Notice how this can interact with the rigidity of OCD. If starting from a rule, it's relatively straightforward to work out the rest of the pattern--it's all unidirectional motion. If starting from bits and pieces, you have to be able to think flexibly, try various possible solutions or approaches on for size, and be able to back out and try a different way pretty easily, instead of getting stuck--it's three-dimensional motion, with many unexpected twists and swerves.
I would encourage you to follow the recommendation of your evaluator and connect with SENG, as well as your state NAGC affiliate. While DYS is an excellent resource for GT learners and their families, it is not the only one, and those organizations who cast a wider net with their target population are not necessarily inferior in their support offerings for any given child.
Depending on your child's needs and educational circumstances, you may also wish to look into requesting an initial evaluation for a 504 accommodation plan or an IEP from your local public school district, as in-school access to mental health supports and any other appropriate accommodations could make a difference in her school experience.
