The podcast you did with "Jess" recently?

I’m the person who worries about their health based on how i’ve taken care of myself in the past. And in that podcast with Jess, she talked about how we affect ourselves on a cellular level with our negative thoughts – which is something I’ve read in other places. I know I’m thinking more positively now, but my brain wants to linger a lot on my health, and what could be hiding in my body… waiting to come out later. So, I am scared a lot. Go to the doctor a lot. And am waiting for ‘the other shoe to drop’ most of the time. Its a constant thought loop in the back of my mind. Do you believe what Jess was saying? And if so, how do I repair this? I’m not even sure I believe it myself.. but its a big source of stress/chatter in my brain.
