What's going on inside of you and around you right now?  Can you simply acknowledge what is there and accept that this is how you feel?
This short guided practice will help you to become familiar with and recognize when certain thoughts, feelings or situations are getting to you.  Learning to systematically check in can provide helpful intel into your own state of mind and how it may be impacting you.  Do this with a sense of curiosity and kindness, building a tolerance to acknowledge and accept what is true for you, it does not need to control you.
