Maybe what you've experienced through your battle with cancer and other parts of your life has taught you something... but this something is currently at least partially obscured because you are afraid of what it means.In the past, when you've tripped, you've taken from those experiences XYZ, and now you're wanting to do so again. But you're afraid to do it and you don't know why. Perhaps--deep down, and not fully integrated--you've already learned that XYZ isn't quite what you thought it was, or at least it doesn't apply to you in the same way anymore. You're not the same person as you were back then. Now you want to experience XYZ again. You are afraid of anesthetizing yourself from what you now know or else afraid of being disappointed in not getting what you feel you need out of the trip.Of course tripping can both delude and enlighten; maybe you shouldn't force it. I suggest waiting until you just want to do it for the sake of celebrating being alive, without expectations of progress, and just see where it goes.
