hi, i know exactly how you feel. i suffer from chest pains all the time, my doctor says it's due to tension but i can't help but wonder that it could be something more. i find that when i have bad thoughts, which is almost all the time, i listen to it and then let it fade to silence and then replace it with a positive thought. if i get an image then i picture it clearly and then let it get smaller and smaller until it has gone, then replace it with a nice image. it's hard but i keep practicing. the other thing that i do is to say affirmations aloud over the negative thoughts, i do it untill i feel more comfortable. i post them up all ove the house. the web sites on affirmation are quite helpful, i copied a few off to keep my brain busy. hope it's been helpful. becca.
