It may be easier to ignore our fear, worry and doubts....but if you truly want to let go of your fear and move past it you must acknolwedge it.
Once you acknoweldge it then you can ask yourself how to move through it. Are there answers for this fear? Is there a possibly solution? You'll be amazed at how much better you will feel once you face your fear and determine that should this fear come true that you do have a solution for it.
Then that fear doesn't seem as bad as you once thought.
