What are some strategies you use to keep intrusive thoughts at bay between therapy sessions?

I do a lot of crossword puzzles! I also journal what I’m feeling. For some reason when I do that it helps the thoughts go away.

Thinking that you need to keep them at bay will only work for so long. That's basically though suppression. Which will make you anxious and that you need to be in control which in fact is an illusion. We aren't in control of most things. Only thing we can control is our focus by being intentional with it. Just remind yourself with compassion that you're not the thoughts that pop into your mind and that thoughts are just thoughts and not a definition of your character or personality. If you feel going down a spiral, with kindness, redirect your focus to something else. We can't control the thoughts but we can decide where to place our focus. You don't need to control the thoughts. That's impossible. Control the reaction to it by focusing on something else that is good. Hope this makes sense and helps

What do you mean by saying keeping your thoughts at bay? If you don’t mind me asking.

Practice not analyzing any of the noise, NO matter what. Instead place your attention on this present moment. Feel your feet on the ground, take a deep breathe, go for a walk, read, go hangout with a close companion, or play a sport. Not avoiding the discomfort, but choosing to do things you want to do and not give any attention to dwelling on that.The most important part being the response prevention. Not easy, but part of the work. When this type of situation occurs and we are in environments in which we are organically exposed to distress, use this as an opportunity to practice doing the work! This allows for two things; showing yourself you can handle and tolerate it, and also letting your body know that although you feel uncomfortable you are willing to keep doing whatever it is you are doing and getting on with your day!
