Your coach said to go no contact because talking does not work -- it makes things worse when your WAS wants space.
One thing I did is to score how I was feeling from 1 - 10, then put a date on the calendar for 1 week or 2 weeks from now. Focus on getting to that date and score yourself again. Note what makes you feel better and do more of that.
The helpless feeling is terrible I know but the DB coach knows what they are doing
