Hi Alicea, I think all DSOs find relationships hard work, relationships of any kind - the superficial relationships that they have are the easiest to fake as these take the least effort - the closer the relationship, the more it drains them and without help, this eventually and inevitably leads to relationship failure. The past haunts all depressives, they ruminate constantly about their past mistakes, big and small and become fixated on their failures, this is why therapy is so important as it helps them to refocus their attention on the present first and then the future, they've forgotten how to do this and need to relearn how to, or if they were never very good at it to start with, then they need to acquire the right tools from a good therapist,
regards,
Erin
