Kalo - I totally understand. When I was caring for my mother, I would go to the gym. That was the one time for myself to try and get everything off my mind for a few minutes. I would take my phone in with me but with earphones on most of the time I couldn't really hear it ring. But I was scared to not have it with me in case something happened. I totally understand that one phone call that could put me in fight or flight mode. One time my mother was on pain meds that lowered her heart rate and blood pressure. The hospice nurse called me and told me that she thought she was transitioning. Immediately my lower back pain increased immensely. I ended up taking her off the pain medicine (it was too strong). In a day or two her blood pressure and heart rate was back to normal. However my back pain was worse for months. It only takes a little trigger.
