I lost my SO. Rather he ended the relationship. His situation sounds a lot like your - extreme workholic, always stressed... exhausted and never any energy to exercise (he used to be a gymnast, but now he is on his way to becoming a skeleton). I wish I had put my foot down and dragged him to a pschiatrist when I still had some power in the relationship.

I think I have lost him forever. Please take action NOW. Don't put it off for another day because you don't want to mess up a good day. I used to do that. Oh, and he loved the vacation we had in December, but right after the vacation he went back to his old ways and got into serious depression after a month.
