It feeds on a deep level of insecurity. Simply, I am not good enough. It stems from my dad who I felt only loved me when I met his standards. I was to going to realize that I needed to find my own self worth. Now, every boss I have ever had automatically plays the role of my father and I go into the I am not good enough anxiety spell. My point, i think we all have underlying issues that creates are anxiety and the solution is therapy along with the meds. My meds help me enough that I am able to get to therapy. My meds are not the answer. I hope this helps someone.
