Anxiety, Overactive mind, insomnia, pulsating tinnitus

Hello,
I am at wit's end- literally. I have generalized anxiety disorder, and have had panic attacks for years, but now I am experiencing waking up at 3 or 4 AM every morning, with my mind just racing. I have a feeling of impending doom, and I also have started having my normal "tinnitus" pulsing in my left ear.
I have been more anxious and depressed than usual- my husband's business is not doing well- and I cannot find a job- so of course I'm in a constant state of worry. With the current state of my health- I'm not sure I could work anyway- so I'd like to get some relief.
I know I should go to the doctor- but do not have the funds, and PLUS I've been trying (over the last couple years) to get off of meds- and to try more alternative treatments for my fibromyalgia and anxiety. I was taking Cymbalta, Lyrica, Maxide, and was also given several other prescriptions that I did not start.
Can anyone give me some advise on how to get my mind to relax- or to stop these unwanted thoughts? I've tried meditation- but my mind is too active to ever be able to shut it off.
Can anyone help me? Please- I'm desperate for a night of good sleep. Tweet
