You've already done the sensible thing - i.e., you'va arranged an appointment for her. To some extent, it is likely she will continue to have some reticence due to her separation anxiety disorder. Such conditions are examples of biologically-based emotional disorders. The apple doesn't fall far from the tree, so to speak. But the condition can be managed perfectly well, and the therapist can help your daughter with some coping skills and can help guide you about how to approach things from the parental point of view. Right now I wouldn't worry too much, if at all, about third grade. Just focus on the immediate future and keep supporting your daughter. It sounds like your instincts are sound.
