I'm so sorry Rainbow
Unfortunately this realization is one of the pains of therapy, even with the best therapist.
I do think that even though we our jobs to our therapist that we are still loved and valued.
Also know that even IF things need to come to an end with this therapist (retirement, death, or rupture) there are many other good therapists out there. THERAPY will always be available, and truthfully loving feelings are more process originating as opposed to working with truly special therapists. Just look at how many similar experiences exist on this board, though we are all very different with very different therapists.
I know this probably isn't super helpful, but you are not alone!
