Help

I am freaking out so badly and not sure what to do. I am freaking out this second, but even worse, I am freaking out in general all the time at least a little. I am so scared of cancer coming back. I have some minor aches and pains and twinges here and there. Yet, I have no serious indication and all statistics point to me being okay for the duration of a long life. Still, I can't shake the insane, gut-wrenching fear. The last few months I've been anxious and then more anxious. But more recently my anxiety has been elevating to panic. I don't know how to not be terrified.
