Hi Pergorative!
Yes...it is true: when I am in in a depression, it feels like I'm on a carrousel of repeats..emotions, feelings, words over & over: staying in the same place.
Just a suggestion: when I am feeling anxious, stressed or depressed I put on my headphones with upbeat music and go for a long walk.
This gives me a change of: scenery, routine, fresh air, sounds, scents...it appeals to ALL my senses. I feel MUCH better afterwards. This technique I have used most of my life..and I do credit it with kick-starting my mood upwards, and a release from the everyday dregs.
There have been days when I have headed out for LONG WALKS (1 hr +) up to 3 x a day....as soon as I feel a mood cycle shift, anxiety or stress..I head out!
Hope this helps a bit....
