Anxiety monster

I keep focusing on certain thoughts and getting stuck in a loop. It's the same issues at work keep happening every day and my mind is swirling them around and I keep getting more and more stressed. I am trying to work through it and not let it out as anger at my co workers. I know that even though the issues are valid my, my reaction is over and beyond what is warranted for the situation. It's really difficult because the same people push my buttons every day but I'm realizing it's my issue to sort out how I am reacting. I would like to project calmness outward and not anger. I have hope because even a year ago I would have had an irrational outburst. I hope it's a sign of growth and managing my emotions s better. I am so grateful for having this place to vent to people who can understand anxiety and the way it can run your life without you.
