I first experienced anxiety after stoping codeine which I was talking for migraine headache pains for about 3 years. At first I didn't know what I was experiencing but easy to work out it was anxiety . It has been 2,5 months and the anxiety is mild now but still there it hasn't gone away. I learned to deal with it and changed my lifestyle to adjust. I know is not medical because I have paid for all blood test to make sure I don't have any underlying conditions that can couse anxiety and panic attack. Now I am trying to quit smoking and went cold turkey like I did with the painkillers which worked for me. However the anxiety and panic attacks are so bad I think I am going to die or go crazy . I really don't know what to do I don't want to smoke any more but at the same time I cannot deal with the anxiety any more. Did anyone went through similar situation , any advice ?
