Hi there delancey,i have experienced that feeling and it really is all to do with anxiety, I have had anxiety and panic attacks for five years long enough but not as long as some,i followed the linden method,and I also take fluxoetine(they are great) and now I am back to "normal" I cannot even bring on anxiety,i have so much stress so many problems(with my teenage children)that I could really have gone mad,but iv taught myself that nothing but nothing is worth worrying about,just yourself and getting better,the linden method has helped me so very much,i listen to a recording every night whilst im getting off to sleep and the help it has given me has been worth every penny and more,if I can help you in any way you can email me, take care and trynot to worry(easyer said than done) x
