You are doing super well, keep up your good work.

If you are using your cbt, step it up a notch - Whats the likelyhood of these health problems happening to you? Now that you eat healthy, exercise and take all your vitamins the likelyhood of you having problems with your health is much lower. Whats the evidence to support your own diagnosis? No looking on doctor google because you then might start to develop symptoms. Is it just one area affected or mulitple symptoms? Is the pain/problem worse when you think about it? Us humans can get ourselves into such a worried state, see how you go with distraction from the problem, if you are distracted long enough does it go away? Is the problem ongoing? Is it a re-occuring worry? Whats the likelyhood right now that you do have this problem when perhaps the last time you did it turned out to be nothing?

Just some questions to ask yourself.
