Talk to you attorneys paralegal. Ask her typically how much of her work is D related? And how she feels the time lines are going (comparatively in your situation), and when she expects to have the first mediation.
Similar in spirit to my previous question/task: Contact the other couple of attorneys you consulted with, ask them what they think of the timelines and how your current attorney is doing?
Depending on their answers, have a conversation with your attorney, and tell her the areas you are feeling neglected/let down.
You received a bill from your attorney, was it itemized? Or was it just a statement?
