You did it!
Congratulations! You made the decision to move on to bigger and better things! however, you may be feeling a bit nervous and uneasy. If you have expressed some uneasiness to your friends, how many times have they said, "But this is what you want, right?". Of course it is what you wanted, but in the end, it is new, it is unfamiliar, it is change. And it is scary. When you have a big unkown in front of you, you feel a great range of emotion. When the excitement abates, fear, doubt and uncertainty remain behind.
People from the outside only really see the EVENT. They see the move to a new city, the new job, the baby bump, the break-up. What they don't see are all of the questions in your head, the various emotions and the second-guessing you may be doing. Even though your friends and family love you dearly, they may tend to brush off your fears with the common response, "it's all going to work out great, you'll be fine!".
When uncertainty strikes, there are steps you can take to combat it. The first thing to do is identify exactly what it is that is making you uneasy. Is it really the move to a new place where you don't know anyone, or is it the fear of leaving everything that is familiar behind? The key to peeling back a few layers is to spend time expressing your anxieties, fears and doubts. It's best to talk them out with a trusted friend, family member or life coach- but choose somebody who isn't just going to listen- choose someone who is able to ask you questions to help you reflect. If that seems intimidating, try journaling until you are ready to talk to someone. Often there are underlying reasons to your fear that you haven't given conscious thought to and simply putting them into words may help you discover some themes you never really noticed.
Once you have identified the thing that is making you uneasy, continue to talk it through with someone who listens well and asks insightful, unbiased questions. You'll be surprised at what you discover - and from there, you can move forward with your fears identified and hopefully set aside so that the excitement of your new endeavor can again shine in limelight.
