Anxiety Support Group
Anxiety is a physical condition marked by intense and persistent feelings of distress, fear, angst or dread. General anxiety caused by routine day-to-day stresses usually passes quickly and is experienced by almost everyone at one time or another.

Only advice I have is to keep rocking at your job as the leadership recognises it so you can move to a different department.

One of the first manager positions I had was the Residence Director of a small Assisted Living Residence in Colorado Springs, CO. When I got there, everything was disorganized and the place was in extremely bad shape. I was in a bad situation because my boss (the Regional Director) had oversight and support of 20 Residences and could not assist me at all. However, I remember that in my previous position with Southwest Airlines, I was feeling stressed out because I did not get the support I needed from my manager. That forced me to learn to be more self-sufficient, which helped me be extremely successful in my next role. What I learned is that God never wastes an opportunity to shape and mold and grow us! We don't always see what is next, or three or four steps down the road, but He does! We have to trust Him.
I am praying for you. God bless you!
