You guys! I did it! I had a breakthrough today.
I was expecting a phone call from my boss and was very anxious about it all day. 
About an hour before the call was scheduled to happen, my heart rate started flying. I did a 5 minute deep breathing exercise, focused on my breath, and got my heart rate back down. Then, a few mins before the call, my heart rate went back up again, my hands started to sweat.  I decided to talk to my anxiety. Why are you here? Why am I feeling this feeling? I took the deepest breath that I took all day and let my anxiety come out with it. The phone call happened and I was calm, collected, and had no anxiety whatsoever (I usually am crazy anxious and shaky when my bosses call me). 


Tldr; I defeated my anxiety through breathwork, self reflection and choosing to do so.
