Dear mindinpieces, I know exactly what you're talking about, I have the same feelings. They come & go throughout my day. What works for me is shifting my thinking by doing something physical, getting busy. This isn't hard to do because I'm a caregiver and there's always something to do. What's really important though is try not to fear these thoughts, then they are magnified 100 times. Just tell yourself that they will pass and they can't hurt you. Thoughts are not real. The mind cannot stay on one thought for too long, we're not programed that way. Take care, and experiment to see what works for you.
