A term I hear used so much these days is anxiety....
.
Now I won't debate whether or not you do actually have anxiety as you are free to define yourself with what ever words you wish.
.
What is important though is to separate the anxiety from the sense of who you are. 
.
You may experience or part of you may have.
I suffer from or I have become your own sense of identity.
.
Anxiety commonly is a fear of what if or what may happen, the revealing of un-reconciled parts or past experiences.
.
When anxiety reveals itself an invitation to hold and embrace that aspect of yourself is being revealed.
