I Have Been On Tramadol 50 Mg 6 Times A

I have been on Tramadol 50 mg 6 times a day since 2003, recently I missed an appointment with doctor and I cannot get it refilled until I am seen which is Feb 3rd. I am on day 6 without tramadol. I have fibromyalgia reason I am on it. I am having very high anxiety and feel like I have drank pot after pot of coffee. Doctor says its just the withdrawal and I will be fine. I am in severe pain. What can I do??? any suggestions?
