My dear that is what the devil wants you to think, it is one of those hindrances that we are bound to comprehend once you are getting closer to your success, life itself is not fair, but you have come to far to quit, many people I know will die for your position which being in the program; wipe your tears and buckle up and move on, find your inner strength you can do it and no amount of course or repeat is worth taking away your joy in the future.
