Yes, especially when I've been thinking about past traumas or going through difficult times. I had a few weeks between different therapists and because I wasn't thinking about it all (as I didn't have to) it got easier to cope and these thoughts became much less frequent. I've only very rarely been in such a bad state that I was really struggling, most of the time it's almost a random thought.
Mine is down to small t trauma/complex PTSD, I go on that forum as well as this one.
Hope your psychiatrist is helping.
