Once you understand what your situation actually is—which is not what that voice in your head says it is—then, of course, you can stop struggling. The situation exists. You don't have to worry about it or drink over it or cry or debate or ask others for advice. You can stop resisting it because what was making you sick was your own thinking about it—not it.
In fact, you're able to go on with your normal activity—and that's where intuition comes in. Because when you connect with stillness, you also connect with a creative intelligence that is higher than analytical thinking. Very often, the right decision then arises spontaneously. It may not happen immediately. It may take your going back to your normal life, but this time period gives your intuition the room and silence it needs to surface.
Ultimately, I believe, whether you choose one way or the other doesn't matter. If you're present when you make your decision, then you'll be present in the next situation—and be ready to make choices as the need comes up. Of course, you always could have done things differently. But the ultimate importance is not what you do, it's how you do it—the state of consciousness brought to the process, which hopefully will let you feel the aliveness of all your experiences.
