on all other levels i think its totally fine, cis people and trans people can clearly understand each other just fine on deep enough levels as long as people are willing to listen.
But therapy, idk, all the roads run through something that is such a core need that every emotional thread eventually winds back to that or passes through it that i dont know how you can ever reach a point of being able to trust their feedback or them to be a neutral meter stick that you can gauge how right side up or upside down you are.
