Suggest Treatment Trigeminal Neuralgia

I signed a contract with my pain management doctor 2 years ago. I recently had an issue where my 8 year old daughter became a victim of a sexual predator and even though the authorities are in control of finding this creep I found my self un able to sleep and my work schedule starts at 4am. So my primary doc prescribed me Xanax to sleep. next thing I know I'm dropped how often should I sign that contract and should I try to tell him the situation? I have trigeminal neuralgia any advise?
