I need help to not feel stuck!!

Recently, I had a worry, then pulled away from it, and tried to let it go by doing something else. A little while after it’s gone, I get a new worry that’s kinda like: “You’re stuck right now and in a “bad time” I feel as if I am stuck right now, and I keep ruminating!! Whenever I get this thought, it triggers lots of rumination. Whenever I get this thought again, It reminds me that im in a “bad time” etc.. Which caused me to stop doing something that I usually do so that it won’t get associated with this time. When I stop thinking about it for awhile, but then it comes back, once again, it kinda reminds me that I’m in a “bad time” if it makes any sense. Does anybody have any tips for how I can stop feeling like I’m in a “bad time”, and how I can stop ruminating? I want to Thank you for reading this, I appreciate it!!
