That does seem a bit unfair -- the clinic has always seemed to be a safe head space for you and now, not so much.

Yep, that's basically it. I have so few medical places that I feel 'safe' in, because of my health trauma of the past, and this is a place I am secure. But as soon as one of my parents steps into a place, I feel guarded again and I shouldn't have to be guarded there.

I really hope it turns out to be less stressful than you anticipate.

I think most of the stress is internal. I felt really self conscious at the last PT session, like "Who here met my dad, who knows he was my dad, what did he touch, did we use the same machines?" etc, etc. Hopefully that will die down, and as long as we never cross paths there, hopefully it'll work itself out.
