Just think of how good you had been doing. Are you going to let this one thing spoil your progress? You must have learned over the years that you mind can trick you into many things. But you managed to put a stop to that for so long. Now you want to start going back down that same old road once more? Ruin everything you worked so hard for. What does your logical mind tell you about this mark? Then we have your HA mind. It will tell you something different. You can easily fall backwards in the HA cycle once more and run to a hospital and have it checked out. To be honest nobody on here would be able to tell you what it is based on what you wrote. A mark on your leg. I have a mark on my leg. My first thoughts are not ' cancer '. My first thoughts are ' oh, a mark on my leg '. Don't let your HA mind take over here. Use your logical mind. Stay on the path you are on. The one were you were doing so good. You were living your life. Enjoying yourself. Don't throw all of that away over a mark on your leg.
