What Causes High Anxiety Attacks And Insomnia?

I was robbed in my home last year on this very weekend. I saw a psych who prescribed temporary Ativan and counseling. After a few months, I was feeling better but decided to return closer to my family. I recently began experiencing high anxiety, insomnia and wondering the house and looking out the windows. I have installed and alarm and can rationalize that my thoughts aren't valid. I am ashamed to discuss this with my new PCP and actually don't have an appt until early March. My shame overwhelms me as I am a professional mental health RN an should be able to snap out of it. Can a doctor please help me at least for the time being?
