The very first thing I teach my clients is the difference between a circumstance and a thought.

A circumstance is a neutral fact that everyone would agree on. For example, if I have a thermometer and it reads 40 ̊F, then I can say it’s 40 ̊F outside. That’s a circumstance. Any person in the world could come over and confirm it’s 40 ̊F outside.
If I say, “it’s cold outside,” that is a thought. Even though I may genuinely experience 40 ̊F as cold, we know it’s a thought because not everyone would agree on it. 
So often, we try to change our circumstances, thinking they are the problem. For instance, if we think the people with whom we work  are difficult, the solution we come up with is to look for a new job.
But what if you could get to the point where you’re completely in charge of managing your emotions, where nothing needed to change for you to feel better? You might still decide to work with a different patient population, but because you want to, not because you feel like a victim of your circumstances.
You move toward managing your emotions by first noticing your thoughts. When you do this, you take on the role of being the watcher of your thoughts.
When you watch your thoughts, you want to come from a place of compassion and curiosity and ask yourself questions like, “I wonder why I’m thinking about it that way?”
You can practice this tone in your self-talk, too. How many times have you thought, “What’s my problem?” versus, “What’s the matter, love?”
Create a safe place to unpack what’s going on in your mind. One great exercise that I highly recommend doing is called the thought download.
For five minutes write non-stop and get all your thoughts out on paper. You can either type it or you can write it out longhand. Either one is fine.
What are the circumstances? What are the thoughts? See if you can identify the difference and allow yourself to get curious instead of judgmental. What comes up for you?
