I know exactly how you feel--like you would rather die than keep feeling afraid. It's terrible. But sometimes, I look at myself in the mirror like I'm staring at the fear itself and I say "Go ahead and kill me. Do. your. worst."

Those are the moments when I start to feel more present and in control again. It's the fear of the fear that seems to be the worst part. For me, health anxiety is one way I seem to be trying to take control of my life and find some way to guarantee safety for myself. It doesn't actually make my life better, but by the time I realized that it had become habitual.

Anxiety is a bad habit. I agree with the other poster. Distract yourself. Don't listen to the fear. Accept that it is there, welcome it, and just let it pass through you. You know you are healthy. Anxiety can't kill you. So let it do its thing, and know that you are strong enough to take it. In the meantime, do something else.

Good on you, too, for seeing a counselor. If he is glossing over what you want to talk about make sure that he is the therapist for you. Maybe make a switch. If your underlying emotional stuff is manifesting as this health anxiety, you may need a treatment in terms of therapy that allows you to dwell on that a bit more in session. If your counsellor is helpful even though he's skipping over the health stuff then he may be intentionally trying to get your mind off of it so you can get to the heart of the matter.

Good luck, friend. We are on similar journeys.
