I would ask the GP about it first and then perhaps they will refer to a Peadiatrician or recommend a good child psychologist to talk to her. She sounds a lot like my son who suffers from an anxiety disorder. The constantly being right on top of you asking question after question. The need to be reassured about every little thing every step of the way. I got to the point of not even asking what DS wanted on his toast as the decision was too much for him. He just couldn't cope. Psychologist has been working with him now for nearly 5 years and helps a lot with strategies for daily situations. Deep breaths and perhaps when she asks questions try asking her 'what do you think?' And see if she can come up with her own answer. It can be so challenging and I totally understand where your coming from.
