I have struggled with that too but then I decided to trust myself. If I don't seem to be able to concentrate on anything then it means that I need. Sure, I would still keep functioning and I wouldn't die but it would be really difficult. If a 2-minute phone call in this situation helps me calm enough so I can concentrate on the things I need to then I definitely need to contact. I have sometimes called several days in a row and sometimes haven't felt the need to do that for months. My T has always trusted my own judgement about my need.
