When I'm frustrated or upset over a situtation, that often triggers my anxiety. I find if I don't start thinking positively about
how to approach and deal with the situation, that my anxiety often turns into anger. Probably because my mind starts racing and I feel out of control over the sitaution. That can lead to me lashing out at people or I just feel like a bottle rocket about
ready to explode. When I was much younger, I probably wouldn't have been able to control myself. My mom used to call it my Irish temper ;), but now I realize it was my anxiety.
Now I usually can figure out now when the anxiety is about to go over the edge toward anger and can calm myself by breathing and focusing on why my thoughts are irrational. That usually stops it in its tracks. You are not alone. I know what you're going through!
