Hi Terry
I get these times too. Combining great comments by Nvr and Clam:
Part of your brain is looking out for the rest of you.
Listen to it.
You take care of yourself and don't get too anxious.
This tends to be my coping strategy now as antidepressants tend to have a very negative effect on me so I have to avoid them. I try to 'savour' the disconnectedness whilst it's there - to relax and go with it instead of fighting against it. I give myself permission to be 'lazy', and have extra treats (Cafe Nero over here!!). I find I can calm down and resume 'normal' life quicker when I do this.
Wishing you peace and wholeness.
