Can you agree to therapy every two weeks and slowly phase it out? Ie. 2 sessions @ 2 weeks, 2 sessions @ 3 weeks,2 @ 4 weeks, 2 @ 6 weeks, 2 @ 8 wks, 2 @12 weeks, 2 at 4 month, than regularly every 6 months.

That way you can tell her your under someone else's care and tell the therapist you want to phase to every 6 months because you have BP but have problems with traditional treatment but your family stresses about it so your solution is to do "check ups" and you'll be honest as long as the session Did schedule stays the same and s/he does not mention medication as it'll result in termination.
