Cloud, this was a very good question and from your answer I get that you are trying to force this 'letting go of ego'. Now the important question (and main problem) is: "Who is trying to let go of the ego?"
The answer is that it is the ego itself! Part of the ego ("spiritual ego") sits on the throne for a while and decides that it is time to let go of the ego. This is impossible, and even if something happens, you're still left with some ego.
So it is always impossible to let go of the ego from motivation by the ego. Any movement of the mind to achieve a result like that is always doomed to failure. This is one of the paradoxes of the spiritual path of course.
About the negative feelings that arise, if you're feeling courageous, just let them be and feel them completely. Usually the feeling will go bye. Then the fog is gone and hopefully you'll enter the higher realms.
Let us know what happens!
