I feel for you as I too am experiencing a bad patch at the moment. The anxiety is constant. I have started back on medication , but it hasn't kicked in as yet. I know that sometimes it feels so bad you think you have something wrong with you, but just know that it will pass and try and go with it for now. Fighting against it makes it worse i think. A couple of things i find helpful are shaking my hands very hard (as if flicking off water), tapping all over my body as hard as i can tolerate and chewing gum ......very quickly...lol. I know these things sound strange, but i personally dont have any success with relaxation methods as i find my mind wanders off. I hope you are able to see a therapist as this can also help. There is a book that has been a god send to me , it is called. "Complete self help for your nerves" by Dr Claire Weekes. There is light at the end of the tunnel, hang in there.
