Tip #1: Take Your Pick
You have a choice how to be ill. You can attempt to carry on as though nothing is wrong and end up killing yourself in the process.

Or you can be a Positive Acceptor: recognizing that your Crohn’s is a card you have been dealt in the poker game of life, but one that will not take away your ability to play your hand to the full.
