Your OP made me so sad on your behalf, and all of ours who work through trauma , I agree it would be more humane if there was an easier way to process without the epic pain that goes with it. I believe if it were physical pain, no one would allow it. It is excruciating to feel that whiplash between the intensity of session and the sense of being cast out after and not cared about- out of sight out of mind. That isn't the truth though. There IS constancy in the caring. The boundaries are there to make the therapy time heightened and extra special/ Impactful to it can work. No they do not love us like family or something; I comfort myself though that the personal life people who have the everyday love probably don't get the pure attention we do. One thing I have found that eases this a little bit is so have a few easier sessions, that don't dwell as much on "the work". If I dig deep down into trauma memories, I leave and I feel like he doesn't care, he leaves me crying in the stairwell , he asked for so much and then left me without a net etc. This is especially true if there are outside stresses. On the other hand, sessions in which the material doesn't overwhelm the relationship, and there is laughter and a lighter topic, the coping skills so taxed by transference kick in and the pain is less. It took me forever to figure that out, and it might not be true for anyone else. There might be a way you can regulate how much a given session taps out your resources for the rest of the week?
