When you've signed up for something, but then regret having done so, or simply don't want to do it, it can obviously be really tough to truly enjoy the experience. But it's a self-fulfilling prophecy. Once the wheels are set in motion, you really shouldn't fight it, doing so only makes the experience worse. Look for the positives in the experience and embrace them, and try to make the most of it. Otherwise your deemed-to-be-miserable experience turns out to be one.
