Something that has helped me is going over stuff in therapy so much that it starts to become second nature when I'm not in therapy and to keep things that I learn in therapy super simple so I can remember them outside of therapy. Such as my therapist gave me a challenging beliefs worksheet to challenge my incorrect beliefs/thoughts and even though I can't remember all the different questions I just ask myself if it's a logical thought, and what the evidence for, and against are. A lot of time I have realized that the certain thought is a little bit of an over reaction to an event but I allow myself to have the thought and not judge myself for the thought but I use reason to challenge that thought. Other times I have realized that the certain thought is very acurate but that I need to stop, slowdown, think, and then act on that thought. Because thinking before acting keeps me from getting into a lot of trouble but now I am catching myself going to the other extreme of not being able to think of the right words to say without yelling and using inappropriate language so I just don't say anything and now I'm starting to stuff again.
