Good Morning Mark and Welcome to HealingWell,
If you have been battling this stomach problem for 3-4 years it is a chronic illness. Most people who have chronic illnesses will have anxiety as their life has changed and change is difficult.
The key to switching out of an anxiety state is to accept it fully. Remaining in the present and accepting your anxiety cause it to disappear.
A:
Accept the anxiety. Welcome it. Don’t fight it. Replace your rejection, anger, and hatred of it with acceptance. By resisting, you’re prolonging the unpleasantness of it. Instead, flow with it. Don’t make it responsible for how you think, feel, and act.
W:
Watch your anxiety. Look at it without judgment – not good, not bad. Rate it on a 0-to-10 scale and watch it go up and down.
Be detached. Remember, you’re not your anxiety. The more you can separate yourself from the experience, the
more you can just watch it.
A:
Act with the anxiety. Act as if you aren’t anxious. Function with it. Slow down if you have to, but keep going. Breathe slowly and normally. If you run from the situation your anxiety will go down, but your fear will go up. If you stay, both your anxiety and your fear will go down.
R:
Repeat the steps. Continue to accept your anxiety, watch it, and act with it until it goes down to a comfortable level. And it will. Just keep repeating these three steps: accept, watch, and act with it.
E:
Expect the best. What you fear the most rarely happens. Recognize that a certain amount of anxiety is normal. By expecting future anxiety you’re putting yourself in a good position to accept it when it comes again.
And if all else fails, kick the anxiety to the curb. 
Stick with us.
